@LucasXu0 I found one issue, and I'm not sure what is the best way to handle it.

When the SelectionMenu overlay is present, you can still change the tab, and it doesn't close. This is less than ideal.

What do you believe to be the best approach to forcefully close it?

[LucasXu0]

@Xazin Let me see. I need to check out your branch to take a look.

Once again thank you for implementing this. In what version can we expect this?

Hey Emmgii, this will be in our next release (0.2.7).

I might be doing a few tweaks to the behavior so that the UX will be more smooth, I expect the refinements to be in 0.2.8.

One important thing to do is to restore tabs that were open prior to closing the app.

Good catch
