At the moment, selecting “fine control” in the “envelopes” section causes the fade-in’s and -outs to also become fine-controllable. Could we have separate toggles for these, please? 
I’d like to have fine control on for envelopes, but not for fades.
Sorry, but I don’t think it’s desirable to complicate the interface with a new option for this case. However, there is a kind of simple solution: this mode can be activated by using the Shift key. In other words, leave this option off in the ribbon. And when you want to modify your envelope with the Find Control, press Shift while using the mouse.
