Long time user, still a big fan of Alt.binz. A (to me and I guess others as well) useful feature would be to have the category selection selectable by keyboard navigation.
Example:
I go on an integrated search engine, find a file to download, press ctrl+d to add the file to the queue and in the popup dialog box I can set the category. However in that dialog box the category button is only selectable by using the mouse. Making it selectable by keyboard(using tab to navigate) would be an improvement I think.
