I looked to see if this had already been requested, but didn't see it.
Since we can't copy and paste elements between sites, it would be nice to have a right-click item available that shows all of the properties associated with that element. (Well, it doesn't have to be available under "right click" but that seemed most intuitive to me.) This is one of the things I miss most having switched from Dreamweaver... you could view at a glance all assigned properties.
This would also be helpful because we currently have to not only scroll up and down to search all attributes, but also across the Styles, Settings, and Interactions windows. That's a lot of searching just to make sure that we assign the same attributes to an element from job to job.
Thanks for having the option available for us to make requests!
