This is like the one thing from WeakAuras I actually like. 

WeakAuras has an option that is defaulted on which inherits the visibility state of the frame that a specific icon/group is anchored to. For example, if I anchor a group to my action bar, if my action bar hides, so will the anchored group. Good for not having to set up a bunch of extraneous visibility conditions on multiple groups.

You can use "miscellaneous > icon is shown" condition to track this. It's not the same as using the anchor group but it's also a bit more flexible.

The only way I could make that work would be to just make an invisible icon with the same visibility conditions as my action bar and then make all icons anchored to the bar have a condition for that icon = shown. Not that hard to do, but a bit superfluous, hence the suggestion for the new option. Or depending on the group itself, I can keep the icon conditions specific to itself, and use the group conditions for all the visibility related stuff.

Probably won't be adding this.
