…But first, let me mention up front that those touchpad gesture improvements I teased last week aren’t quiiiite ready, but they’re very close now. Hopefully next week! In their stead, we have an enormous number of Plasma bugfixes and UI improvements, tons of goodies for KWrite users, and finally a truly colossal number of enhancements for touch-friendliness when in Tablet Mode.
“Hey, what is Tablet Mode?”, you might ask. It’s a feature of the Plasma Wayland session in which everything becomes more touch-friendly. If you have a convertible laptop, it’s activated by flipping back the screen to make it into–you guessed it–a tablet! But it will also trigger on phones and other touch devices without a pointing device, such as the Steam deck as long as no mouse is plugged in (only once it uses the Wayland session, of course).
At the moment it is a Wayland-only feature that requires physical hardware support, but that could change and I personally would be in favor of letting people manually toggle it.
Anyway, get ready for a big one!
15-Minute Bugs Resolved
Current number of bugs: 76, same as last week. 2 added and 2 resolved:
The folder popup you can open to show the contents of folders on the desktop is no longer annoyingly two pixels too narrow to display an additional grid cell (me: Nate Graham, Plasma 5.24.5)
When using a Plasma Vault with the GoCryptFS backend, unlocking the vault now causes it to appear in the Places panel, just like vaults using the CryFS and EncFS backends (Ivan Čukić, Frameworks 5.93)
Current list of bugs. Get cracking! 
New Features
KWrite now internally uses the exact same codebase as Kate but simply turns off a bunch of programmer-centric features. This makes it much more consistent with Kate, more maintainable, and it will have fewer bugs. And now it has tabs! You can read more about it here on the Kate blog (Christoph Cullmann, KWrite 22.08):
The new KWrite, now with tabs!
Picture of the Day wallpapers now lets you preview the image and see image metadata right there in the config window! (Fushan Wen, Plasma 5.25):
You can even click the preview to go to the image’s source URL, or click the little inline save button to save it locally!
Now, when you enter Tablet Mode, all interactive UI elements (including titlebar buttons) that are styled with the Breeze theme become larger and more touchable! (Marco Martin and Arjen Hiemstra, Plasma 5.25:
You can now manually adjust the spacing between Icons-Only Task Manager icons, and when you’re in Tablet Mode, the spacing is automatically set to its highest level for improved touchability, just like we do for System Tray icons (Tanbir Jishan and me: Nate Graham):
In the Plasma X11 session, you can now configure all the buttons of Wacom ExpressKey Remote devices (Someone going by the pseudonym “oioi 555”, wacomtablet 3.3.0):
Bugfixes & Performance Improvements
Monitors in multi-monitor setups once again power off when you disable them (Xaver Hugl, Plasma 5.24.4)
When Discover installs updates for packages that have multiple architectures available (e.g. both 32-bit and 64-bit versions, due to having Steam installed), it now installs the updates for all architectures rather than a pseudo-random set of them, which would blow up your system! 
(Alessandro Astone, Plasma 5.25, but it may be backported to 5.24.5 soon)
kio-fuse now works within the open/save dialogs of sandboxed apps, meaning that you can now use such apps to open and save files to Samba shares and other network locations, for example (Harald Sitter, Plasma 5.25)
Discover now shows the description and license information for local packages (Fushan Wen, Plasma 5.25)
Discover now shows you the correct author name for packages without a specific author set that live in a project group. In practice, this means that a while bunch of KDE apps will now list “KDE” as the author (Nicolas Fella, Plasma 5.25)
The Bing Picture of the Day wallpaper plugin will now download the 4K versions of images if you have a screen with a resolution greater than 1080p (Fushan Wen and Yunhe Guo, Plasma 5.25)
Headings in Plasma widgets once again appear as expected when you’re using the “Breeze Light” or “Breeze Dark” Plasma themes that have hardcoded colors, rather than the “Breeze” Plasma theme that respects your app color scheme (Marco Martin, Frameworks 5.93)
Draggable list items in Kirigami-based apps now move much more smoothly with no jerks or glitches (Tranter Madi, Frameworks 5.93)
User Interface Improvements
When using per-folder view properties in Dolphin, a variety of locations now use more relevant view settings: for example the search view list includes a column shows you the actual location of all matches; the Trash view list view has columns that show the “original location” and “Deletion time”; the “Recent Files” and “Recent Locations” searches group items by day; and so on (Kai Uwe Broulik, Dolphin 22.04):
Tabs in Kate and KWrite no longer fully span the whole window width by default, and the whole tab bar now only appears after a second document is opened, just like in other tabbed KDE apps (Christoph Cullmann, Kate & KWrite 22.08)
Filelight now has a “go to overview” action that will take you back to the homepage (Harald Sitter, Filelight 22.08)
In the Overview effect, you can now swipe down on a window to close it, and window close buttons are now always visible rather than appearing only on hover (Marco Martin, Plasma 5.25)
Notifications for job progress now show a percentage value by the progress bar for those of you who prefer reading text to looking at something visual (Jan Blackquill, Plasma 5.25):
The Margins Separator widget is now much smaller, but becomes larger and more visually obvious in Edit Mode (Tanbir Jishan, Plasma 5.25)
The Audio Volume widget no longer shows virtual devices by default, though you can show them again if you do actually use them (Arjen Hiemstra, Plasma 5.25)
System Settings’ Users page no longer lists a placeholder email address in the “Email Address” field, because it’s 2022 and people generally know what an email address is and how it’s structures (David Edmundson, Plasma 5.25)
Album art in the Media Player widget now smoothly cross-fades when it changes, rather than abruptly blinking (Fushan Wen, Plasma 5.25):
All the Plasma widgets that display placeholder messages when empty now show icons too, in addition to text (Fushan Wen and me: Nate Graham, Plasma 5.25):
System Settings’ Display Configuration page can now tell you exactly what setting a screen to be “Primary” actually does! (me: Nate Graham, Plasma 5.25):
Discover’s “What’s the risk of proprietary software?” sheet is now opened by clicking on a more conventional button, rather than a link that might make you think it’s going to open a web browser (me: Nate Graham, Plasma 5.25):
When you create a new file from Dolphin, the desktop, or anything else that uses the standard “create new file” functionality, the pre-selected part of the filename no longer includes the extension (Fushan Wen, Frameworks 5.93):
…And everything else
This blog only covers the tip of the iceberg! Tons of KDE apps whose development I don’t have time to follow aren’t represented here, and I also don’t mention backend refactoring, improved test coverage, and other changes that are generally not user-facing. If you’re hungry for more, check out https://planet.kde.org, where you can find more news from other KDE contributors.
