I've been using 3DGS for a few weeks now. I've been experimenting and I've liked it. However, the only downside is I have no idea how to use the level editor. I have used quite a few level editors before, the easiest being Valve's hammer editor for the Half Life series.

I just find it too difficult to have to manually add blocks and stretch them from the middle instead of just drag and drop blocks into the editor.

After countless attempts I've given up. Is there an alternative level editor or at least an alternative compiler?
