/**
* Elegant Themes Support Center adds a new item to the [Divi/Divi Builder/Extra] Admin Menu.
*
* System Status
* We will make note of system settings that could potentially cause problems. An extended view (displaying all
* settings we check, not just those with problematic results) can be toggled, with an option to copy this report
* to the clipboard so it can be pasted in a support ticket.
*
* Remote Access
* If this is enabled, Elegant Themes will have limited access to the users site (see new user role below). Further,
* a second toggle appears for the user that will allow them to enable "Admin Access" which has no restrictions
* (Only specific ET Support staff will be able to request that the user enables this). Admin access can be disabled
* at anytime, but is disabled whenever the normal remote access is disabled manually or by timeout. Time left will
* be indicated as well as a way to manually turn off. This will include a description of what this is allowing and
* enabling. A link for initiating a chat https://www.elegantthemes.com/members-area/help/ will also be available.
*
* Divi Documentation & Help
* This will consist of common help videos, articles, and a link to full documentation. This is not meant to be a
* full service documentation center as we don't want to duplicate something we already have elsewhere. It's mainly
* a launch off point. However, if @sofyansitorus builds an easy way to access a searchable list of docs titles in
* his Quick Actions feature, we could add a search bar that would function the same way that searching for docs
* works in Quick Actions (creating a most robust search system is TBD).
*
* Divi Safe Mode
* A quick and easy way for users and support to quickly disable plugins and scripts to see if Divi is the cause of
* an issue. This call to action disables active plugins, custom css, child themes, scripts in integrations tab,
* static css, and combination/minification of CSS and JS. When enabling this, the user will be presented with a
* list of plugins and scripts that will be affected (disabled). Likewise, when disabling it, we will indicate which
* items will be re-enabled. This will basically just put things back the way they were. Site wide (not including
* the VB), there will be a floating indicator in the upper right or left corner of the website that will indicate
* that Safe Mode is enabled and will contain a link that takes you to the Support Page to disabled it.
