Description

Enhancement Summary

Automatically turn AMT to 100 whenever a volume envelope is changed from the default.

Justification

New users to LMMS often do not realise the amount knob has to be turned. If AMT automatically moves to full when an envelope is changed from default, then we have a double advantage: a) user need not look up how to enable envelope etc b) user notices AMT knob going to hundred and can realise what it does.

Research direction
Examine the codebase for envelope handling, particularly in the EnvelopeAndLfoView or InstrumentTrack classes. Review comments on the issue for any proposed approaches. The goal is to detect when a volume envelope is changed from its default state and set the AMT (amount) knob to 100 automatically. Look for existing signal/slot connections that monitor envelope changes.
