Track Icons

One thing I noticed is that if you replace a synth on a track, the track icon does not change.
 
It might be nice if there was a way to have a default track icon set for a synth.  When you replace synth, it would ask you if you want to keep the old icon or substitute it with the default icon for the new synth.
 
For example, on one track I have Addictive Drums, and my track icon is a drumkit.  If I replace that synth with BFD, I probably want to keep the drum icon.
 
On another track, I might have Absynth loaded.  If I swap it out for Rapture, I don't want the track to still have the Absynth icon, but rather the Rapture icon, because it would be confusing if I clicked on the track with an Absynth icon and Rapture came up.
