Comment 10 for bug 992811

Works well here, thanks for implementing the enhancement.

From a user perspective, i would expect the "Lock BPM" option to grey out if the BPM is locked. And vice versa if a the BPM is unlocked, "Unlock BPM" to grey out in the context menu.

And something that bugged me already with the Preview button - Depending on the skin/color scheme, hardcoded icons are sometimes hard to see. Can we style the BPM icon/Preview button using stylesheets in the skin, like we do for the "Played" checkmark?
