Last night we pushed an update that should speed up to-do page rendering and reordering considerably (roughly up to 5x in our benchmarking). The more lists and items you have on the page the more you’ll notice the speed up. Clicking the to-do tab should display the lists faster and reordering items should be a lot smoother.

Special thanks to Sam and Thomas for helping optimize the Javascript to make this happen.

Thanks Jason, Sam, and Thomas (?) for this. I feel like the last 6 months have seen a lot of to-do changes, all positive.

You’re welcome!
