Hi Jeff!
We'are so glad you are getting yourself comfortable with Boutique! Indeed the visualizing of the RGB separations is a great help to se what you are actually doing to the image. It's pretty.
We can call it waveform ?
Dev and GUI design team will look this option among others to see how this can be improved. Thanks a lot for the feedback!
The same goes for the FX preset design. That will be renewed as you mention.
You can actually do that pretty quickly with the Watchfolder functionality of Mistika Workflows.
You could make a Watchfolder node in which you save stills from Boutique in DPX (to retain maximum quality), but then in Mistika Workflows, convert this DPX automatically to PNG (for example) and send it your client by mail. The magic of this, is that this process will be automatically made everytime you set a new DPX in the Watchfolder. Let me know if you need more information about that ?
Here you have a tutorial explaining how it works:
