An idea for the Smart Tool Toolbar
How about adding four (or more) user programmable buttons to the bottom of the Smart Tools Tool bar? These buttons would be able to be bound to a list of Smart Toolbar options. The Preferences Page would be where the user could assign certain Smart Tool characteristics to each button. After the user has assigned a function the button would allow either an icon or a text lable for that button. For example, on Button 1 I would assign that to a Volume Envelope and it may display "Volume" or a suitable volume icon. Button 2 would be a Pan Envelope, Button 3 would be the Mute tool, etc.
The buttons would allow us to create quicker access to certain menu options that may be buried deeper within a drop down menu. Using "T" and one mouse click, I could create a volume envelope and place the track Edit filter in Automation>Volume mode. Or I could get to the Mute tool without having to click the current icon and then navigate a drop down window.
