Does exactly what it claims to do. Advertising a /plot command (while its lack of implementation is mentioned) is a little meh (why advertise it anyway?). More modes and a qalculate-like system would be a huge upgrade (sin(5 deg)), 4+9v=2 [solve v]

The plugin works, offers and functions as written in the description. When I saw the review from WhoAteMyButter, I was really interested. I tested it. It's working.
There is also nothing wrong with the icon being generated by AI. They're not all artists.
And because you mentioned the command of the plugin WorldEdit. You can’t even count the cosine.
I don't know why you're giving a completely stupid review that repels other people.

Disguised theft of Javaluator (LGPL-3), but not licensed accordingly, nor is credit given. Icon is AI-generated (and blatantly at that), and it advertises /plot which isn't available yet (much in "Main Features" but has disclaimer at end; why advertise it?). Ultiamtely, just use WorldEdit's //calc, which is likely faster, better, and not stolen.
