Hi Paul!
Yes, but that doesn't work for me. It's okay on a computer with a mouse, but on my tablet I'm not able to use the slider, I guess my fingers are to tall every time I try it seems I'm missing the slider pin. The the roller shutter starts for a second and moves one centimeter...
I did, but my wife didn't want it that way, see [HELP wanted] A Linear Level Indicator - #49 by Simon01011
