My previous forum - its son lives on XenForo - has such link as "View whole topic". Sometime it is very convenient for visual text finding or whole topic observation. It didn't crashed the server for topics with 500 posts, so I'd like to give my users possibility habitual to them. I hope it is not too hard to add at? And let admin to take care on too long topics.
There are two requirements to see the whole topic:
1) it is convenient to look visually;
2) it is convenient to print all or a fragment.
I think this opportunity should still be implemented, and let the admin decide to include it or not.
