@timconsidine Ah, perhaps you can let them know of the better option?
Looking at their docs https://docs.excalidraw.com/docs/@excalidraw/excalidraw/installation#dimensions-of-excalidraw
It's just an npm install, so should be easy to package for Cloudron and if need be swap out an integration that also uses an npm install by changing the target name in the code, like Cryptpad if they're not interested in a switch.
