In in an old screencast for Plasma Mobile, you seen a demonstration of an on-screen keyboard, it was a working proof of concept, but the interactin was still a bit wonky…
I love when those things happen: The autor of that plasmoid, Bjorn Ruberg (hats off) seen it and wanted to do something about… the result is a completely reworked widget, (that will be shipped with SC 4.5) now it’s faster, it has a way smaller memory footprint and more important is way more accurate now. typing on it has became quite fast.
In this little video it’s shown the keyboard widget working in an external little app that takes over a part of the screen (designed for small mobile devices) on the small Jax10 and on a larger old via-based tablet.
