Hi,
Husky's proposal would move all selected to the target layer and make that the active (current) layer.
But I think that moving entities was not the intention.

Actually, I mean that: You want to draw something that have to be at the same layer of an entity. If you select that entity, its layer will be shown at status line. But, you will have to find that layer among several layers on the layer list.
Indeed, in total I also wasted several hours looking up the specific layer to continue drawing on it.
That is if you don't follow this common drawing practice:
https://www.ribbonsoft.com/en/tutorial- ... ith-layers
Layers are meant to define how your entities look like (color, line type and lineweight).
Only entities with the exact same look are usually put on the same layer.
It should then not be hard to locate the 'Hidden' line layer or the 'Thick' line layer.
Layers are not intended to group things that belong to a specific (sub-) part in a drawing.
For that we should use Blocks.
Two block examples from the standard Library: 'bed_double_180_200' and 'screw'.
The second one is a simplistic side view of a screw drawn on layer 0 and a red centerline on layer 'center'.
That said, I have a slightly adapted organizing system.
I group issues of my design proposals in layers with sub-layers that follow the common practice.
To compare two or some I set the issues main layer 'frozen' property to false.
Organized as groups, one issue would be one and the same block reference and I cannot select the individual entities.
For particular reasons I have to avoid the use of 'Edit Block In Place'.
While comparing issues, I have the same problem in looking up to correct layer to edit further.
I now see that your proposal is also a valid solution for me.
A script that runs on selected, comparing entities layers and then switches to the common layer or failing and reporting different layers.
It would be fairly easy to script and I will see what I can squeeze out of spare time to write something up.

I can already tell that switching the current layer is a double step ... It neads two Undo's (OO) to step back.
Will report back with a link to the posting.
