           Summary: Kinetic Scrolling [Wishlist]
    Classification: Applications
           Product: dolphin
           Version: 22.08.3

  Target Milestone: ---

SUMMARY:
It would be very nice if Dolphin were to implement smooth / kinetic scrolling.
It has become the standard on almost every OS and file manager, yet it is
conspicuously missing from Dolphin. It seems to be missing from QT apps in
general, but for starters, I would LOVE to see it on Dolphin, being that is
where many folks like myself will spend a majority of their time. 

STEPS TO REPRODUCE:
1. Open Dolphin (or any QT app) on a device using a touchpad.
2. Open a folder with a good number of files (e.g. /bin/) 
3. Using two-finger scrolling, swipe quickly downward to get to files that are
beyond the current view.

OBSERVED RESULT:
Movement stops abruptly, giving the impression of jerkiness and sluggishness

EXPECTED RESULT:
Movement should continue smoothly onward after the swipe has ended, employing
inertia, eventually slowing down to a standstill with "friction", otherwise it
should be stopped abruptly if the user places two fingers down again, or swipes
in another direction.  This would give a much more "organic" feel to browsing
files, and would improve the user experience drastically.


SOFTWARE/OS VERSIONS:
Operating System: Kubuntu 22.10
KDE Plasma Version: 5.26.5
KDE Frameworks Version: 5.101.0
Qt Version: 5.15.6
Kernel Version: 5.15.0-10056-tuxedo (64-bit)
Graphics Platform: X11 (and Wayland)



ADDITIONAL INFORMATION
It would be EXTRA wonderful, if - in true KDE fashion - this were a
user-configurable setting. I realize that some people may not want it at all,
and it would be somewhat difficult to arrive at a "default" for length of time
for the scrolling to slow down due to different touch pads and monitors, so
even if it weren't exposed through Settings, it would be lovely to have a
config file where one could tweak pixel scroll distance / friction etc.

Thanks for your time.
