I'm appreciative of the feature to batch delete/tag/assign questions by checking multiple questions. However, the click-box size for the checkbox is really small, and if you accidentally click slightly outside of the box, it goes to the question and all the checkmarks for questions you previously checked-off disappear. See cursor positions below that result in the above described. I suggest making the check box take the entire left of the question.
When clicking delete on an individual question, and box comes up asking to confirm. Another suggestion is to make this box responsive to pressing "Enter" to remove.
