You have this:
function post(url, data, cb) {
GM_xmlhttpRequest({...});
}
I think you want this:
function post(url, data, cb) {
return GM_xmlhttpRequest({...});
}
I could be wrong, but I think an asynchronous GM_xmlhttpRequest always
returns undefined, and a synchronous request always returns the
response object. The return from the callbacks is ignored, so a return
in one of the callbacks is pointless. If you want the callback to do
something with the data it gets, you have do something explicit with
it, which is usually add it to the page somehow.

I think you're right - I forgot about synchronous vs. asynchronous (It's
been a while since I used an xmlhttprequest) It's the onload: function
defined within the command that is executed on completion of the
command, right? So that code needs to specify what to do with
responseText (add it to the page, or call another function to process it).
