Putting a tag on an e-mail collected by Hustle

Hi folks!

I've started to use Hustle and I think that is incredible! Congratulations.

I'd like to ask about three new features:

1. I'd like to put the image as a background of pop-up. It will produce more impactant pop-ups.

2. How can I put the fields on vertical disposition?

3. (EXTREMALLY IMPORTANT!) I need to attribute tags to a contact. It's a very commom feature on email marketing services, and is fundamental to organize lists in groups. Aweber is working on to increment this feature.

I'm substituing the Sumo.me for Hustle, but Sumo.me has this feature, as you can see on image attached. It is very important.

Thanks for your attention.
