Doesn't work with 'nice' urls
This does not work for me when I use 'path' as url format.
In the file cocowidget.js the action url is concatenated using '&action=upload' even when path style urls are used. This will result in a 404 error (since the url will be missing a question mark and so no url parameters will be present).
Perhaps easier to understand with an example: This url (using "path" in the url manager" will obviously not work
cocowidget.js needs to test if there is a query string present and set the first delimiter to "?" or "&" accordingly.
Other than that, thank your for the nice extension !
