Can't add new pages to the web panel/sidebar?

[sortofsleepy]

I might just be blind somehow but for the life of me, i can't seem to find how to add new pages to the web panel / sidebar as of
1.0.1-a.19

Is this a bug or has the function been moved somewhere? I could have swore it was within the web panel ui previously.

Closing cause I just saw #2739 which seems to be what I'm experiencing as well.
