You can already map lighting functions to any MIDI device you want to use:
Unfortunately there is no manual control for fixtures, as this is not a full-fledged / stand-alone lighting control software, but that's not to say there won't be some ability to create static scenes in a future update - just not manual-MIDI-mapped controls.
Additional features like zoom / focus / gobo / etc. are being considered for implementation in a future update.
Thanks for your feedback!
