Surely we can crowdfund this one??

Fantastic layering tool, I applaud your hard work.

If you're up for more work I have some suggestions...

1. Highlight layers for currently selected entity, this would save having to consult the entity info window. Could also include colour coding for sub layers used within the entity.
2. Entity count on layer list. This would help to identify incorrectly assigned layers.
3. Select all entities by layer. Could be a context menu item.
4. Option to remove render feature.

Thanks again
