byzboo brought this up earlier, but I still don't think we have "solved" this. At least, not in a way I'm entirely satisfied with.
I would really like a way to go directly to the most recent unread post in a thread from the page for the forum/subforum it's in.
None of the existing solutions are really satisfactory. Portal->View New Posts just shows the most recently-updated threads, with no way to go to the most recent post (it also shows threads I am not reading, and threads I have already read). Portal->View Your Messages just shows my own posts, and Portal->View Unanswered Messages shows every post I have not responded to. Only the first is anything like what I want.
Opening the topic and then clicking "First unread post" works, but only if I either remember which page the thread was on, or if I start by going to the first page (and thus end up loading an extra page, often image-heavy). If I simply go to the last page, it will assume I've read the previous pages and not direct me back to them if I missed something.
Basically, if what you want to do is see all the new images people have posted, it's a pain in the ass. My current method is to open up thread with unread posts within a given subforum in a new tab, then cycle through each tab and press "First unread post". Takes about twice as many page loads as it should, which can't be good for the server.
This is something phpBB is definitely capable of doing. Many forums have a button next to the thread title, after the page number links, that takes you directly to the most recent unread post in that thread. Something like this would really simplify reading these forums. Perhaps you read them a different way, but this would really help people who read forums the way I do.
Right now, I basically treat this forum as a "read once a day" thing, because it's so hard to check the new posts in the sections I care about (Movies, Gallery, and two threads in General). If you could implement something like this, I could actually keep up with posts more-or-less as they happen, and would probably be more likely to comment because of that.
This isn't a huge, critical issue by any means. If it takes a few weeks for someone to get around to it, that's fine. But it would be a welcome improvement, especially since I've seen other phpBB forums implement it (so I would think there's a plugin readily available for easy installation).
