Thanks 
At the moment it recalculates all flexbox layouts, that are wrapped. But I intend to add e.g. to the Sliders an auto mode, that would switch between LinearHorizontal, LinearVertical and Rotary, if one of its dimension becomes more than 2* the other…
If you have further ideas, let me know. I will make a new post later that day, so we don’t hijack this thread…
