The main CartThrob Subscriptions Dashboard in the EE Control Panel is lacking a Captain Obvious™ feature:
Search.
Search by ID, name, email, etc would be a huge and (I think ) easy improvement.
And not only that, I'd say this is fairly urgent/high-priority. It's a big blindspot.
I have two clients with more than 5,000 subscribers, and the lack of search is a big speed bump in both cases.
