Behavior of "Active topics"
I have just filed a bug report on the behavior of "Active topics" search. It is inconsistent between top and bottom of the page when entries have been read. A topic read at the bottom will reappear at the next "Active topics" search while the entries on the top of the page will not reappear.
See for more details the "bug report on JIRA":https://bugreports.qt-project.org/browse/QTWEBSITE-430
