I'm currently working at a plugin.
There is a widget, which displays different information and under some conditions it displays a link to a special page which combines all the informations.
The widget is working, but I don't know how to create a custom page that I can show in the frontend.
Basically, I want to use the site structure from my theme and just change the "content". It would by nice, if the page could be accessd by links like "mysite.de/?overview".
