Insert a toggle in to User CP

[kh99]

OK, well, let's say you create a single-selection radio button option "Enable this feature" with the options 'Yes' and 'No'. Then you would edit the plugin and add this code:

if ($vbulletin->userinfo['fieldX'] == 'Yes')
{
(existing plugin code)
}

You'd have to do the same for each plugin if there is more than one.

(Also: the code may or may not need a "global $vbulletin;" line at the beginning, depending on the hook location. It doesn't hurt to have it even if it's not needed).
