The idea of this QGIS plugin is to subsume different tools useful during digitizing sessions. Everybody is welcome to add their tools to this collection.
Currently the following tools are contained:
Planned/discussed tools can be found here http://osgeo-org.1560.x6.nabble.com/more-advanced-editing-tools-td5019552.html
This plugin is supposed to have no CAD-like tools which should go into the CADTools plugin, see also http://osgeo-org.1560.x6.nabble.com/Make-QGIS-interact-with-LibreCAD-td5048565.html
The source code can be found here: https://github.com/bstroebl/advancedDigitizingTools
Thanks to everybody joining the discussion and to Stefan Ziegler for CADTools from where I took some code for the management of the plugin.
