Disallow opening same file twice

[krilim]

I would be nice to have an option to disallow opening same file twice. In big projects, some times I open the same file 2 or 3 times and it is a bit messy.

I think this shouldn't take much work to implement - just out of curiosity, how come you open the same file twice -> by calling rmate multiple times with the same file path or by including the same file path multiple times as parameter?

I have a lot of files open in VS Code. When I have so many files open, the tabs become too small to see the full file name. If I've been editing another file for a long time, I might forget that I already opened the file I need and open it again.
