This would make your product more fully featured for us. As it is if a user wishes to take their time to fill out the form and submit later, they have no way to submit the attachments required as well. We will have to supply an alternate email address which is something we wanted to avoid.
We can't share information about our schedule. Please feel free to add or vote on feature ideas:
It is always best to find an existing request that matches yours, but if you need to add a new idea click "Create an idea" under "Actions" in the top right.
