Marvel Customer Insights

1. Add a mini photo editor so that we can deep fry our imported images anytime we want within the app instead of using an external photo editor.Great idea and a great way to prototype but is way to basic to commit any money to, to put it in perspective, you cannot copy and paste elements from one page to the other.

2. When i click on the links on my phone, the blue colour bg of the buttons is a bit too much, i dont need to see where the links are if i am clicking right on themCool, but please, add Undo button, and most importantly, please add a dialog asking to confirm if we really want to delete something or to stop editing the current canvas.

3. Great concept, but not as useful as I had hoped, with no hope for support in the future.All in all it's a good mobile tool for prototyping, however, what bugs me the most is the fact that you can't copy and paste elements.

4. I would even be happy with a "duplicate screen" option at least.Great app, but needs some work.

5. - I created an account on there website using Google log in option.

6. Which It makes it impossible to log in the app using Google account because there is no option to log in with google.

7. - the mobile website, app, and desktop website all have different features, and functionality making it impossible to crossApp appears to be abandoned.

8. - lack of features, no way to create a text field to enter text, or a switch or anything other than a button.

9. The sync does not work so well, after i update the links in my screenshots on my laptop, they are not updating in my phone app.

10. I designed everything on a app called canva the uploaded them and added links to go to different pages using this app.

11. It would be a great improvement for the app if it features custom sizing for user preferences.
