If only I knew about this before trying to wrangle my github to hit a server every time I rendered a puml file ;)

initial message: Just tried it and unfortunately it's not working on my side :/ puml code disappears but isn't replaced by any diagram - no idea why

Re1: hey, thanks for the quick support!
After investigation, I notice that it's not working anywhere, for instance I encounter the issue with your public file:
https://github.com/WillBooster/plantuml-visualizer/blob/master/puml-sample/class.pu

I guess this could come from a plugin clash?

Re2: working like a charm, thanks for your work!

Great! Feature request: "!include" directive being supported for local files (when code from 1 file is used in 2nd file)
