I'm finding it too easy to accidentally delete your #zap presets. I'm used to long-pressing on the ⚡️ button to bring up my presets, which is how Damus works. In Amethyst they look like buttons, so it's intuitive to tap them when you intend to zap someone. However this simply deletes the preset. It would probably be better to have these in a list where you can swipe to delete them or put them in columns so the X button isn't on the zap amount. Maybe even add a confirmation to delete.
