We normally do everything we can to leave existing FoxyCart versions alone. As developers who use hosted software ourselves, we know how frustrating it can be when something you signed up for and are familiar with changes out from under you (or worse: breaks).
We've been putting off this change for a while, but due to the load it creates on our servers when someone views and exports years of data all at once, we're adding pagination to the admin on the Transactions and Subscriptions pages for store versions 030, 031, 032, 040, 050, 051 and 060.
You can view up to 300 transactions/subscriptions at a time. If you're still using a store version impacted by this change, we strongly recommend you upgrade to take advantage of many improvements we've made over the years.
As always, we welcome your feedback below.
Also, the pagination buttons don't take into account your total record count so they aren't as "smart" as the new admin versions.
