I understand your desire for using your own server but I would prefer some way to self host as your server or even Dropbox might disappear at some point. Peer to peer or a self hosted solution (e.g. via Nextcloud) seems more robust. Just food for thought ;)
While you are at it, in addition to &# 8226; (•) my compendium also contains &# 8217; (’) and &# 8212; (—). It would be awesome if you could add these characters as well.
Once again, thank you for your work.
