Hiya,
Maybe these might help you with using the ace FBIDE By Vongodric.
Try Pressing CTRL whilst hovering with the mouse over an #Include "blahblah.bi" This will allow you to open up the relavant file.
Hold down the CTRL key whilst pressing your middle mouse scroll wheel changes the size of the text in the IDE.
Maybe you know some others!?
Cheers,
Clyde.
