One of the pain points we're seeing is that disabling VisualEditor is cumbersome. Even though there's now a user preference to disable the software, going to [[Special:Preferences]] is disruptive to user workflow.
James and I discussed the possibility of adding a switch to the user interface to enable or disable VisualEditor.
This switch might be located in the personal tools section, it might be a sidebar section, or it might be elsewhere. It should be viewable from ?action=view, ?action=edit, and ?veaction=edit.
This switch might affect only VisualEditor or it might affect all "beta" features deployed to Wikimedia wikis.
This switch will be available to both logged-in users and anonymous users.
I believe this is a high priority bug to address.
