At present, /reader just lists everything as is, in full. I'm toying with the idea of collapsing things with summary/details tags to match the look of /start and the labels page. This will condense the river of posts making it easier to scroll and I can expand what I want when I want to read it.
Things may be a bit janky while I get that in but, as I can just reuse the code from those other areas it should be pretty easy to slot in.
I've also not forgotten about the OPML export, I just haven't gotten around to it yet.
I've added the summary/details split to /reader but am not entirely convinced I like it in that context. Also, for some reason I can't fathom, it's not always working even though I know the regex I'm using is valid and should give the result I'm after. I think it's an issue with extensive HTML in item content messing things up.
Maybe I'll sit with it over the weekend and see how I feel after a while.
