Can I remove the Pro Bar from the compose window?
Yes, if you'd like to remove the Pro Bar (top bar of features shown in the compose window), you can do so by clicking the Right Inbox icon at the top right of your screen. You'll then see an option titled 'Configure Right Inbox'. Click the option to 'Disable Pro Bar' in the configuration window. Make sure this option is selected and then click 'Save' at the bottom of the menu to save the changes.
