Screenshot with handwritten annotation to show the affected area

SUMMARY

It seems like the open/save dialog file listing has no touch scroll, see screenshot. Unless I'm missing something obvious, this is making it seemingly near impossible to navigate larger folders since for those the scrollbar will be too tiny to reliably hit with a finger. This means the dialog aren't accessible anymore on touch devices, including convertible laptops or otherwise touch scree laptops used by their users in a more casual way.

I'd also like to give a honorary mention that touch scroll where it does exist in other KDE applications in larger text areas (e.g. konsole main terminal area, kate main text editing area) often seems broken in that it brings up the on-screen keyboard all the time from a scrolling action, often covering a large part of the screen even if the user just toggled it away, even if the scrolled area already had input focus and the user already just toggled the keyboard away: https://bugs.kde.org/show_bug.cgi?id=489672

Those two problems seem to be possibly the biggest showstopper for longer regular touch use right now, at least from my experiments so far.

STEPS TO REPRODUCE

1. Open save/file dialog
2. Try to scroll main listing in the center (see screenshot) with a finger

OBSERVED RESULT

Stuff gets dragged around or somehow selected. It should scroll instead.

EXPECTED RESULT

Touch scroll works in main file listing.
