I guess one good feature would be to give much more freedom to the admin for the customization of his community, so that each one of them could have a unique look. Otherwise most Dolphin communities would look pretty much the same.

I know it's always possible to "simply" edit the code, but what I would like to see in Dolphin 7 is to be able to do all this through the admin panel. For example to be able to manage the content boxes on EVERY single page, not only a few of them like with see more Dolphin 6, (that includes adding custom php boxes).

Dolphin 7 looks great so far on the outside!
(I'm just wondering about the admin panel...)

Keep up the good work! =D
