If when you put something in a spoiler, it wouldn’t be spoiled when you “mouse over” the thread title.
If you could search within the thread you were reading if it were multi-page. For instance, there’s some “name you favorite simpson’s moment” thread and you’ve carefully read the first page, the second page, the third page, the fourth page, the fifth page, the sixth page, the seventh page, the eighth page, the ninth page, the tenth page, but by the time you’re halfway through the eleventh page you start thinking, “did anyone mention sideshow Bob stepping on the rakes? If only I could search this thread for the word ‘rake’ to find out?”
But, that’s probably not up to our hosts, but is rather a function of the software we use, no?
