i think i know how it can be useful when deciding which placement makes us the largest number of perfects . sometimes when i'm too lazy to do the counting in my head , i place the tile , check the animations , remember the number of perfects , immediately undo , then place in the other place , repeat and compare which placement gave has more perfects . if the game showed us the preview of how many perfects would be made on hover , it would be a tiny bit more convenient
i was looking into it briefly and found that the game has some code i can already reuse to find the imperfect tiles and their non-matching sides
yet , i need to see if i can introduce any visual modifications to the tiles without risk of breaking anything
so , i think it's a nice idea and i'll try to do it on the weekend , or i'll let you know if it is too challenging
