Quite often I come to the forums (I don't use RSS except for the front page blog) and look at posts since my last visit. Frequently there are more than I have time to read in the one sitting but next time I come to the site it will show my posts since the previous visit, but not those that I have not read.
Is it possible to implement either or both of the following features to get around this?
1. A drop down list to select view posts since x amount of time, e.g. last hour, last 4 hours, last day, last week, etc.
2. A way of viewing unread posts. Then it is my choice as to whether I mark a post as read because it is of no interest (rare!) or I actually read it (in which case this marks it as read).
