Description

Companion for Cobalt: keyboard shortcuts for bookmarks from any tab, and opening bookmark groups as named Chrome tab groups. Cobalt Companion adds three things to your Cobalt bookmarks. Keyboard shortcuts from any tab: set a shortcut on a bookmark in Cobalt, then press it on any website to open that link instantly. Chrome tab groups: click “Open all” on a bookmark group or a task’s attachments and the links open together in a named, colored tab group. New window: open all of a group’s links together in a fresh browser window, leaving your current one untouched. The extension works with the Cobalt study planner at cobaltstudy.com. It stores only your shortcut list on your device. It does not collect, sell or send your browsing data anywhere.
