To me, KDE is the only desktop environment which provides an acceptable solution for a x64 tablet at the moment. What i'm seriously missing is "swipe with one finger", as we are used with smartphones - just shift the contexts of a window with one finger. At present, swipe with one finger produces a selection (of text eg). This behaviour makes sense in certain contexts, so it should not be omitted completely. My favourite solution would be a gesture controlled switch between both: swipe and select. Please accept my apologies if the feature is already there - I could not find it, neither could folks at manjaro forums.
Applications treat finger events as mouse events, unless they are written to understand finger events. Please report this separately for each application where it makes sense, so work can be tracked individually and distributed to respective developers.
Hm. I cannot really understand you opinion. If you want to use a tablet with KDE, you want EVERY application to answer to finger slide. Is it really the most efficient way to implement that separately to any app in the world? I rather tend to belive that it should be system wide, not sure whether the desktop environment is the best place. Maybe at the end of the day there must be a switch "finger swipe on/off" - or that can be coupled to the existence of a touch screen.
You cannot support this universally, because there is no universal widget for all applications. The best fit would be QScrollView. But then it would need to be implemented in Qt.
Thank you for your suggestion. I filed a RFE at QT bug tracker. https://bugreports.qt.io/browse/QTBUG-82734 Let's see what will happen...
