During the process of installing and activating one of our plugins that may require review of the plugin's documentation it may be better UX if the Docs link opened in its own tab/window.
By having the documentation load in the same tab the user may be able to easily click on the browser back button unfortunately they will most likely lose their place on the documentation page when they need to re-click on the Docs link. This is also a UX concern as the user will need to back out of the plugin settings to access the documentation (again).
By opening in a new tab the user can switch between those tabs to better follow the documentation while choosing the necessary settings/options the plugin may require.
