Thanks for the feedback so far. Top left and y increase down was my unquestioned choice for a long time. Then someone came and changed "easylang" to bottom left

Thanks for the feedback so far. Top left and y increase down was my unquestioned choice for a long time. Then someone came and changed "easylang" to bottom left and said that her daughter would be easier with it. That convinced me and I changed all tutorials and examples to "bottom left". But surprisingly it turned out that many programs became more complicated, many work with row-column grids (game of life, minesweeper, ...) and there the conversion to the y-values is more difficult. Very often the suggestion comes with 0/0 in the center like Scratch. I haven't thought about that yet, because the necessary negative numbers scared me off.
