Add to Favourite (IE) all your subscribed threads . Good that you have started this when you first joined BC. I have just checked how many threads that I have in my subscriptions; It's a whopping 1,709 threads. So, I don't think I would do as you have suggested. .
one of those hiccups i've seen before & the other i'm still seeing; that repeated word showing up in the next line hiccup i've seen a few yrs back, not anymore; and as for the threads which keep on showing up as highlighted in bold (not read), i still see those. Basically that happens in threads which are embedded within several sub-forums (like in the tournaments section). What i do is i've to click on that section/sub-forum a few times, all the way down to the actual thread, until the bold highlight is gone..i never use the "Today's posts" feature, i'd just hit it straight to the main forum and read the threads showing as bold..
