Hello,
I'm quite new at this game, but I already met the problem, that my list of different script modules gets longer and longer, and with that more and more messy and difficult to overview.
In my opinion a hierarchical view of script modules would be an awesome feature. On local file site it can be represented as JS files within folders (like Java files and packages).It's not an absolutely must have feature, tho, just an ease of work which would affect the UX of playing.
