Things DevPro Need.

hi i'ts me loop from devpro/percy.
so i took a look on both games, and it seems that devpro missing very importent things for the gameplay:
1: Holding mouse button A&S  is not really comfortable so the percy got option For holding the Left Mouse= A and Right Mouse= S that make it much more comfortable for the gameplay.
2: Hand Shuffle- well thats option been asking for so many times, but never accomplished.
We Really need it for Hiding top decks, so opponent Cant see if the card that was toping is importent for seting him and using on it MST or somthing like that. 
3: GraveSigins: so that's somthing some people not really notice it,but very importent for the gameplay. so Grave Sigins what is that? - Grave sigin is like while your monster was for example doing speical summon and oppnent using Warning on that monster so that monster cannot be speical summon agian by cards like: Monster Reborn,Call of etc. and Having a Grave Sigin on that monster, so the monster need  a sigin in the graveyard that cannot be using for Speical Summon. 

Well thats all for now, i belive i frogot to mention alot of things but hope to get fast answer thanks.
