Post History

This is a problem that needs no solution. People know how to skip over quotations and recaps. Indeed, people usually skip over quotations and recaps and only go back to look at them if they find themselves lost in the following text. 

Skipping and scanning is fundamental reader behavior. We all do it, and we all know how to do it. We do it easily and without thinking about it. Trying to introduce some other method of handling it will invariably make life more difficult, not less, for the reader, as they will have to stop to figure out what you have done and how it is supposed to work. 

Familiarity is the first pillar of usability. If it ain't broke, don't fix it. You will only make it worse.
