For residential proxies, it would be great to have a feature where we can specify something like minimum bandwidth left and how many Gbs to refill, and then once your account gets to minimum bandwidth left, it will refill the specified GB amount.

Since our bandwidth usage varies each month, we need some automated solution like this, otherwise we have to manually check out bandwidth daily and manually purchase more bandwidth as needed. There have been times where we've run out of bandwidth too.
