I wasn't sure if this was a feature request or not, so my apologies if this doesn't belong in the forum.
We have a client with about 900 subscriptions and growing and anytime we need to research or make edits on the subscription page in the FoxyCart admin it takes almost 30 seconds for the page to load. It's especially painful when going in and out of several subscription "edit" pages. We would love to see pagination implemented on the subscription page along with search and filters similar to the transaction report page to get a decreased load time.
I realize you guys have a lot on your to-do list and our issue may be solved by the upcoming Subscription API release but I wanted to put this out there.
