Hi there,
LVL Edit was stopped for some time. After that I came back... here's some of the results:

Some big UI changes. More 3D Viewport, exploring textures is now a much better experience, panels changes, snapping position to grid. A lot of new things. Trying to make all user experience much simpler but still fun.

Keep fingers crossed for next release...

What I'd like to see are transform handles that allow you to move objects by dragging them, like those in the Unity/Godot/Unreal/etc.

There's definitely a place to add transform handles. I need to find the right method to do it in Firefly.
Here's a latest look into LVL Edit (:
