KDE devs have been quietly working on Plasma Keyboard, a new on-screen keyboard for desktop and mobile part of the “We Care About Your Input” KDE Goals initiative. Although not ready for texting yet, it has been making progress. Hopefully it’ll be in a screen near you soon. Join the effort!

Idk why all on screen keyboard come without tab key in plasma. I have a laptop while in a tablet mode I can’t use terminal at all because there’s no tab key.
