Anyone knows of a method to get rid of, delete or make not visible, those extra folders (OFX, 32 bit floating point, GPU Accelerated, etc) in Vegas 12 VideoFX Window?
These are a permanent part of the interface and can't be removed. They're used for filtering your effects, transitions and media generators.
If you don't like them, you can just select the option to Show All and ignore them. They'll scroll off the panel and you don't even have to look at them.
