The comment on Variation/pattern randomizer on the Play - #10 by icaria36 applies here too. Please focus on one feature at a time. Also focus on the problem you want to solve, and leave the implementation details of potential solution to the Polyend team if they accept the wish and eventually commit to it.
You can edit this wish to focus on one feature, and then create others if you want. Or we can archive this topic and start fresh with a new one. What do you prefer?
