The Bitwig team are quite easy to get hold of and suggest ideas to - they have a dedicated area on there own site
https://answers.bitwig.com/questions/ - Dom has answered over 2000 questions, but there are other Bitwig Dev there as well....KVR/Slutz occasionally has sanity, but I recommend the Bitwig Q/A or direct e-mail rather than posting on forums, it won't help....Only the BWS Dev's can realy help/implement these issues, so go to them directly!
Its realy days with the Grid, I am sure we can all agree that for an initial release (Grid 1) it is pretty impressive and well formed- I much prefer it over MAX 7 and Reaktor for 'most' things musical...but it can (and will) only get better with time and updates 2-3 times a year (I dont think we have ever had less than 3 decent updates a year!)
