Allow JIRA Calendar to be filtered by user, group, role, component, and version

Would like to see the option for a user to create a JIRA calendar that allows them to filter the events from a JIRA project to specifically show a user. These would be very useful on the personal space as a macro that allows the user to quickly see in calendar view or list view items due to them. Similarly filtering by other parameters such as group, role, component would be very useful to teams that integrate multiple spaces to a single JIRA project, and each space is run by a component team, or some other module of the full project. With larger projects and high issue counts, high team counts, the calendar can be overwhelming.
