I like simplicity ad usability of the app, hence stick to it, most likely, permanently. If it pops up to be paid I’d stick to it again.
Here some suggestions on lights widget.
Insdead of having only 5 or 6 light colors, I’d like to see a color/hue wheel / slider to control lights more efficiently.
As one of pioneers of home automation, (including early stages of LinuxMCE), in this field, I can find the limited number of colors per widget very confusing especialy in complex enviroments. Imagine having a ceiling recesseds together with ambient stripes and some C/W hue spots. In order to get every one set to exact color one need several widgets with only 5 or 6 points of color, and nowdays we have controllers which are able to provide thousands, or millions of colors. A wheel/slider per one widged would be great improvement.
