Great! This looks much better! Edit: No, it’s fantastic! 
I would still make a suggestion though. It would be great if there can be different foliage actor groups. This way one can organize all types of swamp grass in one and all types of mountain grass in another. This way when you switch between editing your mountain and your swamp, it will be easier to switch the selection of foliage actors you want to use. Meshes should be allowed to be part of multiple groups. So thing tags, not folders.
Second suggestion: foliage sets (like different landscape actors). This allows you to place different foliage in a different set, so later you can easily select a particular set of foliage (and delete it, for example).
