For big threads or just threads in general, instead of the first 5 pages being an option with the last page. I think it should be the last 5 pages with the first page being the option.
It will be more convient for big threads that are 20 plus pages, so say i miss the forum for a few days instead of going to the last page and work my way back to where i left off, i could go to the 5th from last page and work my way from there.
I doubt anybody uses the first 5 page option for big threads since the thread is so big.
Re: small suggestion
There's a little arrow in a blue circle to the left of the thread title. Click that and it'll take you to the last post you saw.
