Hi there.
I installed this mod today.
I'd like to report what seems to be a bug in the GUI.
If you enable the code editor and then click on the Moon Logic combinator, it opens a GUI that looks like the Arithmetic combinator.
Not that I am having any trouble with it, but it did look a bit odd. https://i.imgur.com/DANJbk6.gif
Didn't realize that child GUI being focused doesn't seem to count for reopening purposes, and never thought to test that.
Should be handled in 0.0.64 by re-creating same MLC GUI with current (potentially not-yet-saved) code in it.
