i found it. for example, go to the 7.3 tech section, and when you go to pic the thread you want to read, scroll down. find a thread that has multiple pages, im looking at one now that says page 1, 2, ALL. if you click that all button, its the same as the show all button your used to.
and imo, its in a better place also. instead of having to load a page, then click the show all and load it again, you just have to load the page once.
