New Gadget: Jira-Filter

I have to log work for issues not assigned to me (assitance, meetings). There is a Jira filter for that purpose and I'd like to have the option to show tickets based on such a filter (instead of adding them to the bookmark list manually). Furthermore "My open tickets" is showing tickets of types that are used by Jira structures (package, orders ...) and I'd like to use a Jira filter instead.
