I would like to have a way to determine whether a user as a document tab open or not. In some case you would like to close a document tab when the user already has this tab opened.
Currently you are not able to determine whether this tab is already open or not. The only way to close the tab when open, is to include a close document process step in your processflow.
It is kind of redundant though, that you have to execute this process step (which costs performance) when the user does not have this tab open.
