I have another case from RC guide. There is the excercise with tiles in chapter 3 and I can't understand two things:
1) In file chapter_3_expressions_end in style editor there is added compose operator which at first glance do absolutely nothing. In guide it doesn't occur, only in the file with finished style. What is it for?
2) When I finished the style, everything works fine, except turning off Horizontal small tiles. When turned off, almost entire row of tiles disappear. The same happens in file with finished style made by Itoo
