DevonThink Pro (DTP) and menulet

I am transitioning from SoHo Notes to DTP. SoHo offers a menulet in the menu-bar allowing to make an immediate search in the SoHo base without having to leave the active internet page or the task in progress. I did not find this option on DTP and I wonder whether it exists (did I miss a step ?) either directly or through an AppleScript or some sort of add-on (even not free !).
Thank you beforehand.

DEVONthink Pro doesn’t include such a menu extra, therefore the only possibility would be to use DEVONsphere Express which can search in DEVONthink Pro’s databases.

Thank you, I am gonna try DEVONsphere Express then.

Tried DT Sphere, it works, convinced, bought it.
Thank you.
