The current templates are often a bit clunky in some ways... especially the mobile responsiveness/display. Maybe have a few more layout options to choose from as well as the ability to turn on/off the features you'd like would be a bonus. Being able to have a video included on any campaign page would be nice too, since videos can be extremely effective for user/donor engagement.
Also, as a web/print designer myself, "make the logo bigger" is not something that you typically hear come out of my mouth, but logo options/sizing could certainly be improved on the current templates.
