test so far..
Ok, so I created a plug-in just like I would any other include:
Create page with feature that is to be a plugin.
Do so in a page that has css and other structural elements to determine proper values.
Next cut only the code wanted in the plugin and paste into new file and save to some directory.
Next use WA Framework Extension to select file as a plugin and insert where needed in some other page.
Benefits so far: Conditional use of an Include.
Will continue to explore... I'm sure there is more than a basic isset conditional function..?
