Really, and its a terrible reason to write an entirely other app, but I just don't like the styling on the tabs :/ That tabbed Windows GUI is just so damn ugly it actually distracts me.
They bothered me too but it's totally fixable with 1 setting.
There's an option to remove the tabs and they become merged into the titlebar (with numbers). It ends up looking like this: https://imgur.com/a/NDgCZFJ
Then you can use Win + 1 or Win + 2 (or other hotkeys) to switch between them.
Right clicking the titlebar also brings up a context menu for accessing the settings and a bunch of other things.
You can enable this style by going to general -> tab bar -> "don't show" (the radio button on the top left).
"Prettyness" seems like such a trivial thing to complain about, but when I spend half my working day staring at something I'd rather it was nice to look at!
