Slightly off-topic since it’s also the case on the “old” composer, but I noticed that when I drag the composer up and down, it’s following the cursor late, and has a choppier animation.
Play at 0.25× speed to see better what I’m talking about.
I suspect it’s a JS/browser limitation and that nothing can be easily optimized?
I’d love to see interface elements reacts near instantly and being animated at 60 fps.
Besides this, after using the new composer for a few days, it’s just better. It has a few “flaws” people agree on (markdown/preview separation, title…), but overall it’s a very nice improvement to something I think is hard to improve. So, great job
