The observant among you may have noticed something slightly different in the list of topics today. I've made a few changes to the "status cell", which is that square to the left of the name of each topic (see below). I'm leaning on that cell even more than before to show subtle bits of information that registered members might find useful.
(The status cell is largely unadorned for those not logged in to the forum).
As mentioned a few posts back, the dog-ears are back, indicating that you've replied to the topic at some point in the past. I've added a new color of dog-ear as well -- purple -- to mirror the "OP" corner that you see while viewing a topic. If you've got a purple dog-ear in the status box, then that indicates that
you posted that topic.
And finally, the background color of the status cell conveys an additional piece of information, though subtly. For topics that have been updated since your previous visit (specifically, when you were last active in a previous session) the status cell takes on a very subtle blue tint. Topics that were updated prior to your last visit will retain the grayer status cell background.
I experimented with a line drawn between two topics to indicate the time of your last visit, but I found the line to be fairly visually imposing. It also had some notable shortcomings, in that there's no way (with the information at hand) to place the line right on a page boundary. It's quite easy, however, to determine if a topic was updated before or after a given time. So that's what I went with.
I hope these changes make it somewhat easier to tell what's going on. I'm slightly concerned that they add to the visual "clutter", but let's live with it for a little while and see if this works.
