Hello, the App works fine with my CURA-sliced gcodes and with a AnyCubic Delta

Hello,
the App works fine with my CURA-sliced gcodes and with a AnyCubic Delta Kossel.
BUT: there is no feedback on the screen about remaining time,x/y/z ccoordinates etc.
Simple question: Why ?
I am using a LUX10 Tablet with Andorid 5

The remaining time is already shown in the status panel (lower right corner). Showing the current x/y/z coordinates is too expensive because of absolute vs relative positioning.
