I searched for this on the forum but couldn't find it but I would have to guess that it has already been requested at some point but if it hasn't then, it would be more efficient if we could clear all guides without having to open the Guides Manager. It takes longer than simply having a clear guides in the menu (or a shortcut) and it is more clicks. I like the power of the guides manager but for something as simple as clearing all guides, I don't need it and I would like to be able to perform the action without having to open the Guides Manager.
Thanks for considering my request,
