In my plugin's options page, I'd like to have custom GET parameters. WordPress already has a "?page=" GET parameter, so simply linking to something like "?myparameter=value" won't work.
I though of reading the "page" parameter, and then linking to something like: "?page=&myparameter=value". This seems workable, but I don't know if its the best practice. The complexity of my plugin really doesn't warrant sub-pages for now.
So is this the best practice or am I missing something?
