Maybe it’s just me but I feel that it’s hard/time consuming to find items from the add menu in the compositor and modifiers/constraints. I really like the way the material selector works with focus on a search field instead of clicking away in submenus.
So this is my proposal for how the add menu could look in the compositor/modifiers/constraints:
Maybe the problem could be solved by having all the items from the compositor available from the spacebar-search.
What is your opinion?
