It would be great when you click on an email from the marketing activities list on the left if it were to show you a thumbnail image of the email. This way you can get at least a general idea of what it looks like or which one it is.
Currently to see any visual information about the email you need to either click edit or preview. It would be nice to see that thumnail so you can at least see if this is relatively the right email, then you could click preview or edit to see further.
Having to click preview or edit wastes a lot of my time when I am searching through old emails I have created and used in the past.
