I use sublime as a copy paste buffer when I need excellent visual regex search and replace. Vscodes regex search has awkward semantics (or at least I don't know them as well as sublimes) so I usually paste things into sublime, edit them with the regexes, then go back to what I was doing. My work has some extensions that only work in vscode so I'm stuck with it but it's good enough. I also never close sublime tabs and it persists them indefinitely with minimal memory usage, so I sometimes go back to grab things I was doing a few days ago. Definitely not the intended use but it works really well for me.
