I created extradimension.al after the party member who was tracking our bag of holding didn’t show one session, and we had no idea what we had. It’s got all the 5e items released under the OGL built in, and it’s built with websockets so any items added or removed are seen in real time by everyone around the table.

Let me know if there’s any features you think would be useful, I’m keen for feedback - especially if you give it a try with your playgroup.
