We've been using UX on our team for a few years now and overall we're pretty happy with the product. We have a LOT or projects in UX pin (50+). One thing I would love to see is improvements to the projects screen. The dividers between project groups aren't very visible and scanning that page can get a bit overwhelming.

I'd love to see an area at the top that shows my last 4-6 projects I've worked on. Typically I'm only working on a handful of items at any give time but having to scroll around and remember what I opened last is a pain.

 I feel like that screen could use a lot of cleaning up for teams that have a lot of projects.
