Excuse me, sometimes I still have to explain to people how to work with the mod editor, because some modders get lost among the number of buttons and start asking for instructions.

For me, the biggest annoyance was that the "upload mod" button didn't work. It took me a whole day to figure out that I needed to create a new mod with the same name, and then it would pull all the data from the folder. In general, the tool is also a bit clunky, but it's still much easier to work with.
Something about it has really hooked me, so I decided to completely recalculate the formula for calculating the stats/strength of monsters and their costs, and accordingly adjust the strength of units/castles. So far, it's going well, although there's still a lot of work to be done to balance everything perfectly.
