I haven't used much this module, so chances are there are really tough bugs in there that require prioritized fixing, but I'm filing my request as I think this is missing from a complete UI and feature set.

My request goes to the Menu Items. While translating the path is already a great UI experience, I would also like to be able to work in parallel on translated menu items and tabs from the level of Views editor. Doing it manually is a nasty way of doing things, especially with regard to maintenance later on.

Anyway I think this is a great leap forward that I've been looking for.
