It's supposed to be good web practice not to link to the page you're on.. so "home" links on the home page shouldn't be links at all.. of course i violate this with the "home" entry on the left menu. but if everyone likes being able to click the big header "club409" to refresh the home page (instead of hitting f5 for example) then i'll put the link back.
with regards to your edits being "trapped in [your] list" i assume you're seeing the results of the "newline to <br> filtering" issue that's already listed.
To expose some gritty details.. I currently store the "newness" in a table with 3 fields:thread_id user_id post_idwhenever someone makes or edits a post it inserts entries in that table.
Whenever a user loads a url that looks like /post/view/{NUM} that table is checked for any entry matching the current user and that post ID. but this is the *only* time that entries might be removed from that table meaning if you browse to a thread page (i.e. the link in the parens on the main page) it doesn't check the table and doesn't clear the newness.
I realize this is different from the expected behavior given the previous implementation and I plan on fixing it soon.
