IDE Suggestion... any takers? - Collasapable Code Segments

Yeah a poll would be great,
I think a better scenario is to handle tabs better ( open and close tabs from a sketch folder view ) allowing smaller source files, but maintaining manageability. I have combined a few of my library files just to reduce the number of tabs ( it is in sketch folder while I develop it ). I don't really have a need for any other IDE apart for this reason. Still using the Arduino IDE though.
