FluentCart questions—thanks for your help!

Hi there!

I installed the free version, and I like it, but I have a few questions:

1. In the Pro version, is it possible to delete and reorder checkout fields?

2. For subscriptions, can I manually change the next payment renewal date?

3. Is there a subscription saver feature (if the discount option is canceled, etc.)?

4. Is cart abandonment a separate plugin or built-in? I can’t find it.

5.If a customer purchased a subscription (via Stripe) for $1, and I later change the monthly subscription fee to $2, will the price also change for those who purchased it earlier?

6. WooSub and WooCommerce Membership work together. If someone’s subscription expires and isn’t renewed, the membership is automatically suspended. How does this work here? We don’t use FluentCRM; we use something else. Do we need an automation plugin, like UncannyAutomator?

7.For subscription-based services, can users change their credit card information on my website? I can't find it.

8. In what ways, why, and by how much is this plugin faster than WooCommerce + WooCommerce Subscriptions? Are there any tests on this? Or if there are already 100,000 subscription renewals, does it slow down just the same? If not, then why not?

Thanks a lot!
