Buggy is fine, I’ll find another way and fix it. Transition not smooth is fine, at least it still work and I’ll reduce the complexity of my prototype. But I just don’t understand why the tab bar works terribly. Had to keep tapping it until it works. That is not ok at all.
Tried it on a newer version of iPhone and it has a larger screen. When it’s not resized the tab bar works perfectly. Once it’s resized(the tab bar again is at the bottom of the screen), it doesn’t work anymore.
Please fix it. Even though it’s buggy and slow (both this preview app and desktop app), I still think it’s one of the best prototyping tool. I really like that I can control the logic and make it like a real app. That makes it a great usability testing tool. Hope the team can put more effort on it and make it better for everyone :)
