For events like Sanrio Virtual Fes and virtual conventions happening in VRChat, it would be great to be able to access instances directly from VRChat. Currently you have to go to your web browser and click on an instance for an event, look at the event schedule, etc. For those wearing VR headsets and not using OVRToolkit or another window overlay, it means constantly taking off your headset and searching the event website for what to do.
It would be great to have a small window on your menu that acts as an event pass. If you are part of the event, you can scroll through the available worlds for the event, and join directly from VRChat. It would be as simple as checking event registration (which can be done currently, as Sanrio Virtual Fes tells you in their world if you have a ticket through XMarket) and then providing the world links in the pass window instead of going to the event website.
