IDEA!

Interesting, they would have to probably make some pieces faded or something, so you would know which ones you don’t have. +1

-1 . it seems helpful and cool but in real its just further modifications which helps those people who sacsit out there. time is an important element and if such a feature is introduced, time wont be a deciding factor anymore. i'd say its a horrible idea and spoils the game many a time. after all, if time scrambles are going to be so easy that u can premove invisible pieces, why even keep a clock there?
What if you could premove placing a piece before you had it? So when you would look at your pieces that you could place, it would have a 0 next to any pieces you didn't have. But you could premove that (even if it was your turn) so the second u got it, you would place it. This will help in time scrambles that are very close.
