[Moved from wishlist and edited.]
From 2.4.5316, the Toolbar button spec has been changed. And I feel it very unuseful.
I have assigned "Playback: Replay Gain Toggle" function to a button.
Old versions worked well (one of four labels is displayed showing replay gain state), however, this version just assumes ON and OFF of each button.
And, the button works somewhat odd: button text does not match with actual replay gain state: always both ON and OFF labels.
- Can assign more than two button labels.
- Displays one of multiple button states.
- Can assign only two button labels.
- Cannot display button states.
So, please restore the Toolbar button spec to the previous version.
