Cool Addons Menu is an addon for Blender from Kito Studio that automatically identifies your activated addons and lists them in one place. Only addons that have a panel in the N-Panel are listed, and the list updates dynamically when you install, uninstall, or enable and disable addons. Entries are shown alphabetically with the current version listed beside each name.
Clicking an addon opens its panel, and a gear button opens that addon's preferences configuration page. A "Sort by N-Panel tabs" checkbox groups addons by the tab they belong to, with tabs listed alphabetically and the number of addons shown after each tab name. A search field filters the list to addons whose names contain the string you type, and an x button clears the filter.
Cool Addons Menu also keeps a "Recently used" area showing the last five addons you reached through it, from which you can open an addon's UI panel or preferences page the same way as the main list. Documentation is included, and a demo video is available.
