The Notes box on the right hand side of the Activity screen seems strangely limited to a fraction of the available space
If you type something that takes more space than the white box you need an additional click to get into the full description. Is it possible to extend it to take up all the available space? In the screenshot above this would take the top white box down towards the “Today” bubble. I expect if there are lots of comments on the activity then maybe that needs to take up more space as well, so maybe they will end up with 50% each of the yellowish box.
