Can we get convert hbd from savings?

While I see the point, I don't really think it's worth the effort to implement unless there is a significant request for it.

When I look at payouts the order is descending payouts, can we get that changed to chronological?

Hmm what do you mean ? Sounds like a front end thing

Invite friends/followers to communities would be nice.
Maybe a notification of being invited?
Opt in/out of notifications.

noted, thanks :)
