I love the ability to save DSP chains by right clicking the track.
However, it would be nice to actually be able to load them from the same place. So if you right click, Load DSP Chain -> should have a tree menu that is propagated from the file system structure.
Load DSP Chain > Drums Guitars\ My Chain 1 My Chain 2 Synth leads FX
A dialog box can pop up saying Do you want to replace/append/cancel
And perhaps saving of DSP chains can be handled in the same way.
