Not so much of a requested app, but I happen to utilize in my personal case; multiple versions of Opera or OperaGX.
It would be nice to have the ability to change the icon colors so it is more discernible which version or instance I or anyone else is using.
My actual use is for Auctions and it can get quite confusing, if I am on my (Bidding) version or my (Just Browsing) version, when they are virtually identical in every way, but what I am using them for.
Just a thought?
I have tried changing them myself, but no software I have encountered can save the file properly and the browser locks up.
Thanks and these are some great Apps here
