Does not work. Search box remains the same.
This review is for a previous version of the add-on (3.1).please tell which operating system and addon version. As of now, it is working in TB 91.2.1 on Win 10 pro. Preferably, leave more info in the github issues section https://github.com/opto/Expression-Search-NG/issues.
