Well i know Jon is very busy as he's working alone, but i thought it would be good to write here about something i love. In fact i almost moved one of my sites to dotclear (dotclear.net) (even though it's not a blog hosting app by default) almost only for this feature.
What i love in dotclear is the generated template system, there is a simple template that can be customized with just a few clicks, you choose the background color or image, some other colors, a header color/or image, you can specify many things (like the number of columns) and then it generates your CSS file which is stored in your upload folder.. It is just fantastic for all the newbies that have blogs and want to change of template..
I thought it would be great to propose this.. Maybe in the future someone can do that..
