Make lightning the default payment method for bitcoin payments - currently it is on-chain.
This will be cheaper for end users and also for Kagi, avoiding on-chain feed.
Improve documentation for new user going from free plan - it is not obvious that you need to select a plan on the other screen - this will avoid support calls and user frustration
It would be best to have Lightning as the default payment for bitcoin - this will be easiest and cheapest for everyone. Currently the default is on-chain. I did not notice this when I made my payment and ended up with high on-chain fees and Kagi too will have fees to use the small amounts. Lightning solves this.
Also when going from the free trial my payment did not seem to do anything - I had to contact support to be told that it is first necessary to select a plan (it is obvious when you think about it) - that is not obvious for new users
