Thanks for the feedback.
Your MusicBee panel is quite narrow in that screenshot. Is that a limitation of your display, or a deliberate choice of yours?
Do you have some Windows display scaling active?
I agree the wavebar can turnout a bit narrow at smaller widths. But I have designed it for modern widescreen displays.
I'll see if I can maybe adjust it a little bit, but I can't promise I will change it.
Ideally the left and right border of the wavebar would get adjusted dynamically depending on the panel width, but I have experimented with such in the past, and pretty much always failed in getting desired results.
2. 'inconsistent' bar
It is not inconsistent in the sense that you have disabled the header for that panel, and the bar retains the original colour of the header bar.
Making it any darker would have a negative effect on the header bar when unhidden.
But you could use a piggyback skin to change it.https://getmusicbee.com/forum/index.php?topic=29815.0
Or create a wish to perhaps have it slightly less tall. (which I would probably support)
That's indeed a personal preference, and I prefer to have them unhidden.
Perhaps something could be done by using a piggyback skin.
Maybe I'll try that out. (but don't hold your breath)
And I see you created a wish for a feature regarding this, so let's see…
