Having a simplified Render Layer editor would be great for those of us not working on large complex multi-user scenes. Functionality along the lines of the Legacy Render Layers would be all we need. Yes, this can be set in Maya.env, but it would be better and more stable to have this integrated into and compatible with the modernized Render Setup framework.
I think many users would benefit and ADSK could demonstrate some welcome consideration for individuals, smaller studios and the Design community in general.
This should be fairly simple as its more about hiding features than adding new ones - and if you need the power, just turn on the full-featured version.
For example - name based collections? too much - if its in a render layer, layer - render it, if not don't.
Difficult to set up layer overrides like before - if I only need a few of them, the legacy method was far simpler and more direct. The new Render Setup has unnecessarily complicated and limited my workflow in this regard.
