Update:

The CSS i wrote in my post seems to work, but not when i use \tag to write notes in my margins

I remixed it from another case, ill see if i can upload it somewhere tomorrow.

Thanks! Sounds very solid!

Does this setup have some sort of versioning or snapshots?

Thanks, did not occur to me to use a dedicated app for that purpose! Will check that out.

I want to avoid having anything private or critical be internet facing.
