+  * vk-driver: Handle CTRL modifier
+  * vk-driver: Handle KEY_{COPY,PASTE} as copy/paste keys
+  * input-surface: Add copy/paste buttons.
+    Let's see how this works out. E.g. it won't work in terminals.
+  * ci: Update Debian image
+  * osk-widget: Unblur icons.
+    I've had these in screenshots and that doesn't look nice.
