As always, I started hacking into the joomsuite recources components and field plugins. I made it so it no longer displays nor sends the file with the preceding timestamp in it.
Now it is looking nice.
Next step will probably be to make it seofriendly url, not for the SEO part but for my greasemonkey section where in order to install the scripts in firefox and IE they need to have the filename in the url as last element and as a file not parameter.
So, more hacking to be done in the following days.
