Thanks for the replies, but none of the suggestions are helpful with what I'm trying to do, which is to **open a new tab** (empty "untitled" file, or a new buffer as @elextr said) **in an existing instance** (any existing instance, I just don't want to spawn a new one).
technically it opens a new buffer, it doesn't actually create the file until you save the buffer
And thanks for that, because I tried calling `geany ""` and it started editing `/home/<username>` which... ouch. XD
I think this issue could probably be closed as you can do what the title says already.
...no, I can't? Unless you choose to interpret it as "open existing file in a new tab" which, okay, but not what I meant.
Oh, well. Is there any official way of submitting a feature request for this?
