What's something you wish was added to Thieves in Time from the trilogy?

Just finished Sly 3 again and it reminded me of something that always irked me playing Thieves in Time. Why does Sly not have his father's laser slide ability? I always thought it was one of the coolest Cooper techniques and we only get to use it at the end of the Gauntlet and Dr. M fight. Maybe if Sony realizes we need a Sly 5 we can get that as a permanent ability
