"GX corner" tabs on Opera GX should be ignored.

Wrongfully lists "GX corner" as duplicates but they're integral to Opera GX. It's a small issue, but it would be nice to get fixed because each Opera GX window will have that tab. 2So if you have 3 windows open, these will be listed as duplicates (which they are, but these tabs cannot be closed hence they should be ignored)

Allow exceptions

I and others use various "new tabs" - which want to remain open on various browser windows. It is annoying to have to dodge these on Duplicate Tabs and the program would be much improved if adding exceptions were allowed.

Prevent Duplicate Tabs + Suspended Tabs


Our teams work with a massive number of active google docs at same time.
1. Your duplicate tab prevention tool helps tremendously !
2. So does other tools that suspend tabs after short period of inactivity.

However they don’t work well together. Your duplicate tab tool does not detect duplicates between an active and suspended tab. The url of the active tab is usually encoded in the url of the suspended tab. And it would be life saving for our teams if your awesome tool was able to detect a tab in either state, e.g. try to open a link to a doc (that’s already open but suspended) and it automatically closes that tab and brings you to the suspended tab. Heaven.

For example an active URL:

- Here is an example of this suspended tab URL with The Great Suspender (fixed secure version):

- Here is an example of this suspended tab URL with Tab Suspender:

Please consider this enhancement for me, my teams and everyone else trying to get the most out of their heavily used Chrome browsers.

Whitelist the "New Tab" ("Neuer Tab" in german)

Is it possible to whitelist the "New Tab"? Sometimes I use multiple of these tabs and everytime it is already open then the new one gets closed and my last tab is getting opened.

I already tried: New Tab, Neuer Tab, chrome://newtab and chrome-search://local-ntp/local-ntp.html

Are there any other things I can try?
Thank you very much!

Best regards
