Great addon but it is missing one important thing; an option that organizes suggestions/results/bookmarks in groups. Right now everything is mixed up together and it ruins what could be an outstanding experience. Please consider including such organization features.This review is for a previous version of the add-on (0.7.25.20140626.1-signed.1-signed).
Omnibar defaults' to Firefox's default method of presenting and organizing search engines. To keep things simple, Omnibar does not have any plans to add any form of custom organization features other than those provided by Firefox's "Manage Search Engines'. If you would like to make it happen, you might consider contributing to https://github.com/ajitk/omnibar. Thanks!
