Which widgets-sorts have control features for access
(referring to the remark in the description: "..You can make certain widgets only visible to members or non-members..") ?
I would be looking for plain text widgets that can be made visible to members or just the opposite: non-members.
I already tried to use shortcode, [nonmember] and [/nonmember] in the text widget, but that did not work.
As far, I am convinced that your plugin still is a "must have" in my standard collection...
