Don't go away yet! From top of my head, here are mine!
Behaviours:
Solid Plus - switch on or off collisions only between selected objects. Also support for isometric objects.
RTS Plus - Moving objects can avoid each other, too not to bump or overlap each other.
Array Plus - you can name columns and rows for ease of requesting data.
Isometric Movement - For rts or iso kb/pad controlled games. Allows to set different speeds to different directions. Specifying at what angles those directions are. Also, eventually, allows for slightly bend turning if two directional buttons are held (for example: forward and right if controlling char trough kb or pad )
Ladder/Bridge - self explanatory
Plugins:
Easy Menu - a plugin that easily lets you create menu's. Whatever can be done in ide, the rest can be set by events.

Dialog Progression ( for text ) - a plugin that lets you easily display text in succession. Additional option to create choices that appear underneath the displayed txt. ( ref. rpg maker )
