1. It's cleaner and doesn't feel bloated
2. It's open source.
However I wish:
3. They would have some consistency between mobile (iOS) and extension (Safari) UI (because imho extension actually looks like a mobile UI, I find iOS UI less useable)
4. They would do away with load time that I often notice when I open extension even though data is stored locally.
5. It doesn't maintain state or save info when I leave the extension popped up and then move away and come back to it. Also, It also doesn't save auto generated passwords with the "url" it was generated on which often renders password history useless.
6. For everything I have to reach all the way to the browser bar extension button and I don't get any option in the text field itself which was pretty good in LastPass.
I wanted to move to KeePass and while it has an excellent app for desktop (native MacPass is fantastic!), but I could hardly find anything even close to useable for Safari or iOS.
