I'll skip the bugs in the dialog; hopefully they will be fixed as it is tweaked.
What I would like to request is that we have a couple more canned reasons. Just about the only reason why I hit the "Other" option is to supply one of the following rejection reasons:
- Deleting your question would penalize those who made the effort to help you.
- Used when someone wants to delete a question because they are ashamed of how dumb or simple it is
- You can provide an answer and (after a waiting period) select it as correct to close the question
- Used when someone wants to delete an already answered question as they have solved it themselves
