I think it’s an interesting and very useful feature. But, I see the same problem as with Drawer Navigator: if you don’t see it you don’t know you can use it. I mean, if theres is no menu or additional button, as a final user, you see the first screen but you don’t know that there is another one you can navigate to.
And this leads me to another, and for me critical issue: closing screens. Specially for Android, if you can’t close screens, you may be leaving a lot of them open as you navigate through the app. If someone starts pressing the go back button (or sliding back in IOS) he will see all the outdated info of all the unclosed screens he previously left.
This may lead to malfunctioning due to some outdated data, cofusion for the user, and it doesn’t look very pro. I haven’t found a solution for that.
With all the awesome stuff that you are creating, I think this would be pretty easy to solve for you. Isn’t it?
Thank you very much.
