In IntelliJ 9.0, is there any way to hide the panels on the sides and bottom? Specifically, I'm trying to hide the Ant Build panel, since I don't use Ant and don't want to have these extra panels taking up space on my side and bottom bars.
You can permanently remove the Ant Build panel by disabling the plugin. Go to Settings > Plugins and uncheck the "Enable" box next to Ant Support.
