What are the ways in which I can look for videos on PeerTube instances?

I’ve been trying to venture into using PeerTube more – as a watcher. But, so far, I haven’t seen how to ‘explore’ for different videos.

What is the default sort order of the videos from Peertube instances?

And, is there a way of pooling of the videos from different instances?

Love the app, anyway.

Thank you Devs for all the effort and great app!
