I'd like to suggest an improved layer grouping functionality. Currently, it is very difficult to regroup a layer without breaking apart an entire group and then regroup everything. This can be very labor-intensive if you are working on a power apps with many screens and layers. I would think a model where you could drag and drop a layer would be an optimal solution to this problem. Or at least the option on right-click on individual layers to remove or add them to a group.
