can you please provide a screenshot of the content of your twiz folder?
I downloaded all suggested plugins but am not sure which files I need to upload.
oh and what is the purpose of the admin button inside your plugin? if I click it there is a pop up asking me what are the features I want within the administration panel? Is this some kind of a survey?
btw I realize I can only select between two conditions on where to show/load the effects, how about some more options like the http://wordpress.org/extend/plugins/widget-logic/ uses? (conditional tags)
