In VS Code, when I open another file, or create a new one (ctrl+n), said file open next to the currently selected tab. I would like this to behave the way browsers do. Well, at least the way firefox/chrome do for me.
I find I am dragging tabs around a lot because my file look ups end up inserted between my order of other files. 
I want it to instead always open the files as the last tab, the same way all my browsers do.
Ideally I would still like definitions to open in the next tab instead of the last, i.e., again, the way browsers do it.
I can't seem to find any settings for this, and I didn't find useful search results, just a bunch of stuff around not having the quick view tabs that get updated.
