[sergi0g]

I am sorry for the off topic but is it possible to have the cup version number somewhere in the webui?

Hey @Superuser18,
Thanks for opening this issue!

I like this idea! I'll find a way to get that info when building the frontend (along with the commit hash) and include it at the bottom of the page.

Much appreciated
