3 missing features, though better config UI than Redirector Rated 4 out of 5 stars

I like this add-on. But it seems that there are missing features.
1. Import/Export (Low priority)
2. Support for tabs opened by links outside browser like mailers or shortcuts (High priority). LocationMorph 1.1 doesn't rewrite its URL.
3. Accessibility via Tool Menu and icon on addonbar or toolbar (Middle priority).

This review is for a previous version of the add-on (1.1.1-signed.1-signed).
