This is my humble attempt to start a list of user requested API ideas/enhancements/additions to Lua.
I suggest anyone posting here attempt to suggest their idea in a format that mirrors the ML Lua API documentation (see mine in this post).
I suggest this thread is not the place to debate the worth or even practicality of the API suggestion. Let's leave that for another place, once a Lua API 'uplift project' gets going. This thread is about ideas/needs/wants. Having said that, I suggest anyone posting here think about their need or use case, ie let's try and be sensible ;-)
The following are a few of my personal suggestions to get us going (note I have deliberately kept formatting simple, ie not complicating the posts with HTML:
