Mail panel disappears when opening the closed windows from the window panel

[Yamo]

So here are the 2 problems that I noticed today when I opened my laptop after returning from work.

1. Mail panel alongside other panels disappears entirely when I open the closed windows from the window panel.
2. It appears that something was messed up with my bookmarks, I made a folder and put it in the bookmark bar now it's in the more bookmarks and it has only 1 after it had a lot of bookmarks so I can't really seem to get wtf happened.

@Yamo Mail panel can only be visible and operable in a single window at a time, at present. Operational conflicts presented by multiple windows are not yet solved.

Oh, okay then, and what about the bookmarks that was messed up?

[Ayespy]

@Yamo "More Bookmarks" is a Chrome thing, not Vivaldi. Do you know how you got a More Bookmarks folder?

[Yamo]

Could you elaborate more?

[Ayespy]

@Yamo Nevermind. I was thinking of the "Other Bookmarks" folder. Did you perchance import bookmarks? And from what browser?

[Yamo]

What I am suspecting has happened is that when I synced up it got messed up, even though I have done the last change like a week or two ago.

@Ayespy I didn't do anything of that, unless if you're talking about like 2 years ago or something, other than that it was messed up for an unknown reason to me I believe.
