Just checked MacVim again and it looks like it's a setting in preferences. (Called "open files from applications" but applies to file menu too). Happy to leave as is, maybe add a pref later.
I wanted to capture this in its own issue so it doesn't get lost. (As a side note, is there currently a good place for neovim-dot-app to put GUI-specific user preferences like this?)
Yes, this kind of thing is handled by functions defined in nvimrc. So we might have MacSetOpenFilePreference('new-tab') for example, and users would put that in their vimrcs.
