Hello Roshan,
Thanks for submitting your idea. However, this is something that we are already doing.
After each event, we download the recording, upload it to YouTube and then add it to the event page. Because it involves multiple teams, it takes a bit longer (from 1 to 2 weeks).
Nonetheless, we are updating all event pages with the past events.
The Multi-Tenancy one will soon be there as well! We'll send a message to the group once it's uploaded :)
