It annoys me that when you change the setting in "your threads", it also automatically changes the setting in the main board. Because the number of threads I have participated in are usually fewer than the actual number, I often want to go back further there than I would like to on the main board. Couple this with long loading time for the boards when there are too many posts...

I don't know whether this would be difficult or easy to do, though. It is only an annoyance, but it would be great to have it changed.
