No major frustrations with the ux. If you are asking, a small nice-to-have would be an [add] button next to mints, rather than having to copy and paste the url. My 15,000 sats did disappear from the npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv mint I joined, but I consider the 15,000 sats to be a donation to the tech build out, which I am cool with - Minibits were very clear it was experimental. See the last transaction being a deposit but balance is 0 sats.
