I designed Hazzy to fill an entire 1024x768 screen, so if you have launcher panels or anything else that takes up screen real estate it will not fit. I am currently working on making the UI salable to fit different screens sizes and resolutions, so I should have the resolved eventually.
The 'tools' symbol in the gremlin controls is suposed to bring up the same menu as when you right click gremlin, but I had some trouble making that work so it does nothing at the moment. Hopefully those controls (and others) will be in a popover menu some time soon.
I have physical potentiomenter based Feed, Speed and Rapid ORs on my machine, but I am planning to add on screen overrides to Hazzy as soon as I figure out were to put them!
I am currently trying to migrate the from GTK2 to GTK3 for the UI, which will give me a lot more flexibility in how the on screen controls can be done. I am also thinking about maybe completely changing the UI design to make it more touch friendly and easier to customize. I hope to post some mock ups in the near future for you all the criticize. Thinking maybe more like a CELOS control, but without all that flashy appy junk...
