Add round brackets to starting characters?

[itogst]

Could you add round brackets to the characters that are allowed to be before the @ of a citation?
I'm not quite sure why round brackets wouldn't be allowed to be in front of @.
If there is any reason I would be happy to know!

It's a great extansion otherwise!
Thanks in advance

Good question. I actually don't remember exactly why I excluded round brackets, but I think it was to avoid accidentally writing (@smith) instead of [@smith].

Pandoc's citeproc should format the citation and insert round brackets if necessary. So if you want the final document to look something like This is a proven fact. (Smith (1994)), then it's better to use ... fact. [@smith94] instead of ... fact. (@smith94).
Although both versions might give the same output by default, only the square bracket version will be formatted correctly if a different csl file is used.

I guess if you wanted to add an in-line citation as the first thing inside a round bracket, so something like This is a fact (Smith (1994) proved it), then the extension wouldn't show the suggestions.

Anyways, if you think allowing round brackets will be useful, then I can enable them.
