To be able to select two or more sequential pages and combine them into one page

I am not sure if this was possible in previous versions or not, but as of LoadComplete 3.2 at least, it is possible to delete pages (right click > delete). The requests from the deleted page will be moved to the previous page, except in the case of deleting the first page in your scenario, in which case the requests will be moved to the subsequent page, which has just become the first page. :)
