1) The available height options are 180 or 150 cm. If, instead of the middle 1×30 cm piece, there were two 15 cm pieces (or even three 10 cm ones), there would be more flexibility in possible heights. The lamp might be a bit more expensive, but it would offer many more options.
2) The touch control is VERY sensitive, but you can get used to it. I would appreciate at least a subtle separation between the individual buttons.
