I agree with the sentiment about the update. My gripes aren't to do with adding comments, but with the list view.

Since about yesterday, it feels like the UI has gotten more bloated and now has a lot more empty white space. I can fit fewer tasks on my screen at once, and it feels like I have to scroll and scroll to see the actual useful things.

I also find it distracting how some UI elements disappear or appear as I'm moving my cursor through a list view. There were elements that did this before, but this new update seems to have added even more of them. In particular the " + Add Task" buttons at the bottom of list sections now disappear when the user's cursor moves too far from the tasks in the list view.
