1) I would like to have BP menu separated, and some kind of close/open button for open "Shared BluePrints". So after open blueprint dialog via "B" you've been seeing just your Blueprints and after click on "Open/close" button, it should "open" (rolled up) left side menu with "Shared blueprints". So "Shared blueprints" should be hidden for most of the time. 2) It would be awesome to have some kind of small editor of blueprints in preview of your current blueprint Mainly for adding more stuff to blueprint, not only remove them.
What do you think? Would you like it too? But maybe I'm wrong, just an ideas I want to tell

Have a nice time.
