When soloing group suggestion

Add 2 3 4 channels in one folder and route all channels to 1 group (for example, back vocals)
When you hit SOLO on that group, folder remains “muted” (but channels inside are not).
If folder is “minimized”, you can’t see that there are inside channels that are playing.
When you have 80 channels, that can be time consuming to find those channels.
Maybe it would be great idea to have mute icon blink, or solo icon blink ON the folder when this situation occurs, showing that there are channels inside that “layer” that are playing.
It would be much easier to find channels you just soloed
Thanks !
