Possibility to modify settings on Mod and Dly/Rev knobs as it is in FUSE.
Small changes and fixes to make saving effects work properly - fixes issue 8
Why don't you put 'Save to Mod' button on Effect2 slot, and 'Save to Delay' on Effect3, and 'Save to Reverb' on Effect4?
Because Delay and Reverb can be both set on one slot and with buttons in the effect windows this would be impossible.
