Feature: extend vrchat:// protocol to allow opening in client group UI, preferably with option to choose tab (instances, group info...).
My use case for this feature is to reduce steps player have to take from vrc.tl event page to joining group and finding instance of event. Currently on vrc.tl event page I provide link for opening group page on https://vrchat.com/home, but I also received requests to add "copy group short code to clipboard" button, which indicates some players want to join groups directly trough client instead of in browser. Having option to open group UI directly based on group ID would remove need for group searching.
I believe there can be also many other good use cases found for opening other parts of client UI (event, player, avatar, store, settings...) directly from browser.
