I'm not sure what the plans are for this mod, but it'd be nice if all generating flowers could be tweaked similar to those already covered by the mod.

Additionally, if possible, the ability to adjust the mana capacity of a flower, as that directly caps how much the flower can realistically produce.

Hey, sorry for the late reply but I just noticed the issue (Haven't been that active on this mod).
I was planning to add support to all generating flowers, however some of them may be impossible and, since it's a lot of work, I was hoping that the requests came some flowers at a time, not all of them together.
I'll see what I can do, but it depends on whether I'll start developing this mod again)

Unfortunately the mana capacity is capped at the mana generation, and there's no way to change that.
