Could we have a function to skip through a thread looking at all posts by OP? Or a 'collapsed view' which showed only OP posts?Think this would help a lot with 'cancel the cheque' / RTFT issues.
I set my view so that OP posts are highlighted a different colour but still means lots of scrolling on long threads, particular ball-ache on mobile. A work around is to do 'find in page' on the OPs name but if lots of people have addressed them by name that isn't very helpful.
