I read this from Giancarlo in another thread:
Is it possible to make a "wish list" for features in Nebula 4, or have you already "locked" the list of features and just working day and night to reach your deadline?since version 1.3.619 (to be released) it is possible to create a skin with a really small lcd (only preset name is supported) and no other displays. Alternatively you could disable all lcd at once even now. It happens because nebula is supporting things coming from upcomng product nebula4, to be released on november 2014 [my marking]. For this reason we are constantly improving the skinning engine, and also old nebula3 is taking advantage of this.
If you find a skin developer tell him to contact me and I'll provide syntax, so when 1.3.619 will be release everything will be ready
With all the nice skins coming up lately, it would really have been a great feature to be able to right click and assign the knobs to MIDI, so that we could have the Nebula sound and hardware feeling turning a real knob.
Is it possible to see the list of what Nebula 4 will bring to the table?
