Thanks to usbpoweredfridge, Thomas, and date, who took a look at the 3.1.3 beta 1.
Here's the second and last beta of the 3.1.3 version.
In this version, we improved the tag drag&drop feature according to the feedback received.
Mar 18, 2016 - Version 3.1.3 Beta2
In this version:
Enhancements:
- Drag-and-dropping of tags within the Tag sidebar
-  Esc now cancels drag and drop operation
 -  More clearly visible and wider drop hint lines
 -  Fixed bug caused by pressing Alt+Tab during drag & drop
 -  Added ability to drop before the first and after the last tag         
 
 -  Esc now cancels drag and drop operation
 - Option to use single Tab press to insert TAB character instead of Ctrl+Tab (see "Options/Editor/Tab Character" menu)
 
Fixes:
- Clipping: backlinks to documents were not always added even when they were present in the process's command line
 - CN didn't restore to maximized size from system tray
 - Link to file not copied properly if path contained non-ASCII characters
 - Notes count control was cut off at 120 DPI
 - Display scaling caused CintaNotes to crash in Windows 10
 - Unnecessary save confirmation on pressing Esc in empty new note
 - "Database locked" error when CN was used on a network share
