Nowadays, it seems like it’s a war for space with all of the plugins available in Gmail. We try to make our plugin play nice with everyone, but in the event that it doesn’t you can use our settings menu to turn off any conflicting features.
To access your settings, click on the Crystal logo for the extension on the top righthand corner of Chrome:
Unselecting “Gmail” will remove Crystal from your compose/reply window in Gmail entirely.
Unselecting “Underline Suggestions” will prevent Crystal from automatically underlining suggested changes in Gmail.
Unselecting “Gmail Sidebar” will remove Crystal’s personality sidebar from Gmail.
