There are a couple of small changes I'd like to see Plimus implement:
1. A search function for the forum. If I were running Plimus, I'd see this as a business decision. A proper, searchable forum would surely lighten the load on the support staff, because they'd spend less time answering the basic questions that must come up again and again.
2. I'd like to be able to do a $1 trial (or whatever amount I want - for instance 'Free plus Shipping') for 7 days, 14 days or whatever, followed by monthly billing. Plimus will let me bill every 14 days, or every month, but I'd like the period before the first billing cycle to be flexible.
3. A progress bar on the Download file upload page. "You will see no change to the page until the upload is complete." Duh.
