Not a big thing, but since we work a lot with screenshots for incidents and mockups for changes we basically daily need to upload files one by one in your attachment function.
Would make our work so much easier if we could upload multiple files at the same time and especially drag-n-drop them in to the tickets.
Hope that it could be implemented pretty fast since it normally is easy to implement the multiple attribute in html. Would be nice to have and your competitors both supports multiple files and drag-n-drop. Hopefully in the future this can be done, and I hope more of your users agree with me.
