Can the Close Arm button be moved? I sometimes use attachments such as a light shield that I printed, and I just accidentally hit the huge Close Arm button when trying to hit the link to the seestar at the top of the app. Fortunately it had lost connection to the tablet so it didn't do it, but the potential for disaster is there if it tries to close with an attachment at the front of the lens. Nice feature, especially the Open Arm to make it easier to add filters and so on., but the location of the button is unfortunate. A sensor to stop the close would be good as well if it meets resistance to avoid borking the gears or whatever damage that may be caused.
