However, some of the naming / functionality is a bit odd on the widget "settings" and I hope this will be fixed.
The author confuses the use of "pages" and "posts" in the settings, using them somewhat interchangeably in the setting language, which makes it confusing.
My need was to disable the widget from showing on a specific page, so you would think "hide on specifics pages" would offer this functionality. Nope. He only allows you to select "posts" by IDs, under setting that refers to pages ... or hide for ALL pages.
functionality needs to be updated and language clarified, then would be perfect useful plugin.
It seems the functionality logic is probably there, but the settings need to be updated for the next version. I guess I am going to have to hack it for what I need it to do.
