After some time I went back and reviewed the WP-Stripe plugin to see what changes have been made. There were some good features added so I proceeded to merge those into Card-Stripe.
Some of the html changes were a bit problematic as the current audience for Card-Stripe use Windows XT and IE 6 (at best).
Moved to using a button to pop a modal dialog box (jQuery ui-dialog) and tightened up user feed back on what is required and validated during the key entry of a payment. Also re wrote the paging position feedback and added First and Last buttons too.
