I have been taking a looky look into kdenlive to see if I can use it as my new main video editor and I have noticed that both Krita and Kdenlive and remarkably similar, like more than I could imagine them to be.
However here and there some things are different and some are actually good ideas that could also work for Krita since it has the same basis for the most part I think.
you can change the theme and the style:
The Environment Setup:
ffmpeg alignment to be used.
external folder for organization though pulling from 2 folder for each would make more sense since it seems to force you to opt from the system folder and user defined one, either way it works.
external editors. This comes in line with the interconnection of programs I occasionally speak of it is not just blender.
waveform rendering on the widgets is possible and can be analyzed I assume since it is a KDE project too.
