Hi, did anyone notice such bug with Adobe Acrobat 2020?

When I want to compare 2 PDF files in Acrobat, I use Window-Tile-Vertically to position them in parallel.

However, once with Acrobat in the Groupy, one PDF file will disappear. (not shown on the screen.)

I can see it in the tab of toolbar, which shows there are 2 files opened, but you can only find one, even with app switcher...

I can only close Acrobat, and then open it again to find such window.

(Currently the solution is to exclude Acrobat in Groupy, but not that convenient.)

Also want a function like Chrome, once I mistakenly closed a tab in Chrome, I used Ctrl+Shift+T to re-open it.

I believe Groupy should offer the same feature, which is very convenient for all users.

If anyone knows how to and let me know, I would be really grateful.
