[Feature Request] Add option to select browser to open in.

[miclgael]

Thanks @gharlan for this workflow, I use it daily :)

In my setup, I have modified action.php:20 like so:

exec('open -a Firefox\ Developer\ Edition '.$query);

To tell macOS to open my query in a specific browser. I thought this might be a cool / easily implementable feature.

I do not want to add a config for this, sorry. I think default browser will fit for most people.
