I've changed the code in the lab so that when a sub is subbed, it shows at the end of the menu or, if full, in "More" dropdown menu.

The only problem is you'll have to arrange all your subs again (only once).

Edit: there's not need to rearrange the subs anymore.

I haven't tried it. But I agree, if I subscribe to a new sub, I likely wouldn't want it to end up in my customized sub bar unless I decide I want it there.

I wouldn't mind rearranging my subscribed subs but don't know how.
