I noticed some concepts in Qedy ain't right. For instance, I always perceived Modal window as a separate entity, but in fact it's just bit more complicated QView. This also once again confirms, that my choice of just four component types (elem, form, list, view) is indeed sufficient.
Similar problem was with various frontend perks, like content prefetching or smooth scrolling. I added prefetch to an ordinary QList as f_prefetch feature and I created some extensions (“plugins”) for QView_Page.
