Great Plugin, Just a Few Questions

I’ve been using the Subscriptions for WooCommerce plugin for a while now, and overall I’m impressed. The setup process was simple, and I like that it doesn’t require coding skills. The support for recurring billing, flexible cycles, and the integration with Stripe and PayPal makes it a solid solution for subscription-based products.

Here are a few things I’d love clarification or improvement on:

1. Free Trials + Sign-Up Fees Together?
   Is it possible to offer both a free trial and a sign-up fee at the same time? I’d like to give users a trial period but still charge an upfront setup fee.
2. Renewal Reminders for Customers?
   Are there email reminders or notifications sent to customers before a subscription renews? If not, is this something planned for future updates?
3. Failed Payment Handling:
   What happens when a payment fails?
   • Does the plugin automatically retry?
   • How many attempts are made?
   • Can we customize the retry schedule?
4. Compatibility with Other Membership Plugins?
   Apart from the official Membership for WooCommerce plugin, does this support integration with other popular tools like MemberPress or Paid Memberships Pro?
5. Upgrade Path to Pro:
   If I start with the free version and later move to Pro, will all my settings and subscriptions migrate smoothly without interruption?
6. Custom Fields or Add-ons for Subscription Products?
   Is there a way to add custom fields or options for subscription products (e.g., gift notes, delivery instructions) within the subscription flow?
