Wishes: more layout options

[phmarek]

Hi,

thanks for the useful utility! I've got a few ideas that I'd be happy to see, though:

• Optional left/right rulers with zero point in the middle
• Polar resp. cartesic coordinate systems
  • Center and axis directions calibrate-able (parallel to sides or arbitrary angles, non-orthogonal axis, center off-screen)
  • Store multiple calibrations
    • Make them available as quick options via long press on app icon?
  • Allow center point to optionally move in a grid only (eg. only every cm)
• Level display (horizontal, vertical, angle, ...)

That would allow to calibrate an axis to the exact border of the smartphone (including cover!) to take markings parallel to that border, or orthogonal, etc.

Thanks a lot!
