I have the add-on [https://addons.mozilla.org/en-US/firefox/addon/tab-stats/ Tab Stats]. This lists and groups tabs by unique domain or unique URL listing duplicates in a separate sub-tree. On each url item there is listed the last access date/time. Is it possible to get a list and group tabs by last accessed date? I've put in a request on the extension for this feature - [https://github.com/glandium/tabstats/issues/14 New tree - List by age exponentially] but the authors appear inactive and unresponsive. What is the best way to encourage development of this feature if not available in pre-existing extension or feature (which is preferred of course)?
