why not doing the follwing as concerning scripting:
1. ability to add one or more event-buttons with particular caption which should execute a certain, userdefined function on the chosen event-id
2. (probably already integrated, but since I don't know scripting yet, I don't know it): feature to
add (is the only thing I need for what I wanna do, but to be more feature-rich also the ability of deleting a category would be nice) a category to a passed event id.
so it would be able to connect both things to add a category by rightclicking.
This would be an awesome feature since it would make speedup hiding events which are done by adding a category which is marked in options to now be shown

WONDERFUL!!
thanks so far!
p.s.: nice new board!
