IOS critique and thoughts, solutions, and features.

So I picked up armor paint on the iPad and I've had a few issues. My biggest issue is right now the app doesn't feel great to use. I have a few ideas on how to improve this.
First make one finger inputs orbit the object. Right now if you drag one finger across the canvas nothing happens, but as soon as that finger hits the object it paints on it. To orbit the canvas you have to use two fingers. Which means you either have to constantly lift your stylus off the screen to orbit, or you have to have both hands on the iPad at all times.
I think one finger to orbit, two fingers to zoom or pan, and 3 fingers to rotate the environment lights would be good shortcuts.
Another thing is in the upper right of the view port there is a gizmo that displays which direction is xyz. I'd make that a cube and give us the ability to drag it to rotate our model. Kind of like zbrush let's you rotate that little bust icon.
Two finger tap to undo and three finger tap to redo would be nice too. I'd try to minimize keyboard inputs as much as possible. The big appeal of the iPad is that you can work on it without having to reach over a keyboard.
I'd also make a stylus only mode, in this mode only pen inputs would draw on your object. Anytime you touched the screen with your fingers it would just move the camera. I accidentally drew on my model a lot just trying to orbit the camera. Having a dedicated icon just to focus your icon would be good too. The camera bugged out one time and I completely lost sight of my model, if I had a key board I could probably have just hit f to focus it but without a keyboard I literally had to abandon the project.
Also I'd make the app come with a few brushes and materials by default. I know that there are some located in the cloud folders, but it feels kinda yucky to open the brush menu or material menu and have nothing there at all. Giving us an option to autodownload all cloud materials would be choice.
I also had some trouble importing models into the program. One time I tried and just got flickering black screen. I believe that was with an .stl. I also tried importing a sculpt and the program couldn't handle it, after about 2 minutes it would crash on import. Now to be fair the sculpt was 1.5 million polys so I wasn't expecting a miracle. But having a warning message or an error message pop up and telling us why the model might not import would be helpful.
So if I were you I'd open the app on the iPad, unplug the keyboard, and see what you can and can't do without one. Then I'd make gestures or touch buttons to make up for those keyboard shortcuts. Having a radial shortcut menu that we can assign keyboard shortcuts to could be a solution as well. As of right now I won't be using armor paint on my iPad. But I am very invested in it's development (literally I spent 17 big ones in it lol) and I would like to one day be able to comfortably lay in bed, sit on the couch, or PBR paint on the go. I can tell this is a powerful PBR painter but it needs a little more elbow grease.

Thanks for these suggestions, it really helped even though so many years have passed already. I have implemented some of these already in the latest ios update, and will continue to implement the rest.

Man that's awesome! I'll give armor paint another try soon! As for the time it took I totally understand since you're a solo dev (I think) there's a lot to juggle. Thanks for being receptive to feedback!
