Show Attachement Symbol for documents, links
If there are any documents or links attached to an activity, allow the possibility to activate/deactivate showing a symbol (e.g. paperclip, mini-globe) beside/on the task (automated artifact functionality).
It helps the business user to see the relevant documents/links promtly, instead of clicking on each activity (searching the documents/links).
PS: Links and documents are one of the best arguments (beside workflow usage), that business user go in the process description. Therefore the accessibility should be as easy as possible.
