aras, 
Someone, uhh, accidentally convinced me to look at #blender video sequencer.
I know absolutely nothing about video, sequencers, timelines, composition or these parts of Blender codebase. Which is to say, perfect! :)
Just landed for Blender 4.1, make drawing UI of complex timelines 4x faster https://projects.blender.org/blender/blender/pulls/115311
But also, I started to look into related parts, and oof, now I want to speed up like 300 other parts. Which one to start with first?
