   - Tx channels
   - Possibility to connect channels for example Rx to Tx or single Rx channel to dual Rx channel supporting MI(MO) features like 360 degree polarization detection.
   - Specialize plugins into channel and sample source plugins since both have almost complete different requirements and only little in common

   - 32 bit samples for the Channel Analyzer
   - Enhance presets management (Edit, Move, Import/Export from/to human readable format like JSON).
