Just landed a few changes on Patantara -
The names (URLs) of documents and attachments are now much shorter and much less intimidating.
Some UI tweaks in the editor to help with the process of adding attachments. When you now drag-drop a file, the label of the reference created will be automatically selected so that you can change it immediately to something that is more meaningful in the context of the document.
(UPDATE 7 Apr 2014) Got rid of the modal alerts during the file upload process and replaced them with an unintrusive notifications panel.
