Sounds like you were busy over the weekend
I have started work on the editors, but I was quickly side-swiped by how run-down the GUI has become. So I started refurbishing the GUI and writing documentation as I went. You can find it in the wiki and try it out in the dev branch.
I did manage to put in some scaffolding for the editors. They open with the console - separated by tabs. The editors will load everything they do as a module into a separate module manager (to keep the actual game stuff away from the editors stuff). I did the same thing with the assets. The editor assets are loaded by a different asset manager instance. This should make it much easier to build an asset editor.
So there are lots of code changes to the GUI and many of the controls are still broken or I removed them (there were 9 buttons). You can read about my changes so far here:

I also did several Patreon post about my changes that you could read.

I took a break from the editors to do an update to my game, but the update is almost done and I'll return to the editors soon.
