I also like a nice clean look. The only thing I noticed (I’m a new GP Pro user) is my inability to find a menu item or button that would allow me to see a list of all threads I started or have subscribed to (i.e. follow/get notifications about). I can live with this, but it would be nice.
The thing I find fascinating is the incredible amount of support provided by GP staff. It’s amazing that you help people with non-GP problems (e.g. “What’s the CSS syntax for…”) β quite often these types of questions get ignored. After all, there are websites devoted to answering such questions.
You also have an extremely large group of people coming to ask questions!
