Would be nice to have the Soft Synth in use to match the track colour it is used in, or is this not possible because a Soft Synth can be used by multiple tracks?  I also noticed if I change the name of an FX in the list of Soft Synths the name is not changed in the FX bin - is this how it is supposed to be??
 

I'd load a color icon into the synth rack.

How do you load a colour icon into the synth rack? I see an option to set icon as default or something but nothing there I can find to load..

Click "Load Synth Icon..." in the right-click menu and then navigate to the Colors folder in the Track Icons folder to choose a desired color icon.

Btw, a forum member (ston) kindly created additional color icons in the following thread. I don't know if the files are still downloadable, though.
