Hello!
When viewing an item or subitem where it opens the panel on the right side, the tabs for "Updates" "Files" etc. are too small. During mouse-over the 3-dot menu takes up so much of the smaller ones ("Files") it's almost hard to just click the tab.
I get it you're trying to maximize space, but maybe this is a little too cramped here. Mostly thinking of my users who don't do great with technology and don't realize the difference between those being two separate click-surfaces.
