Visual indicator between a layer and a group
In the layers panel, a group and a layer look the same in appearance. Thus, when a named group un-grouped accidently, it loses its name. This mostly occurs due to lack of visual dissimilarity between and group and layer thumbnail. May be a small marker in the corner of the thumbnail (indicating whether its a layer or a group) should do the trick.

Yes. Since the behaviour is so different, and that difference can be vital if, for example, you're handling layers and groups differently in an asset export script. Not being able to tell the difference at a glance in the layers pannel is a big PITA.

Definitely need the ability to recognize group vs. layer at a glance in the layers panel.
