in DTTG one can tap to select a document and tap again to untap or deselect the document. The result was the app displays the document content in the main window. After untapping the document content was not displayed any more.
In DTTG 3 this is no longer the case. I am not able to deselect aka untap a document to end its content shown.
Miss I something or is this functionality gone in version 3? In the latter case this will be a feature request.
