I think rogues should get tricks like a fighters manuevers. I was thinking of a way to give it a resource without introducing something too new or copying manuevers die. So I thought of tying uses to the number of sneak attack die.

Rogues would be able to apply effects to creatures affected by their sneak attack. They gain a number of uses per day equal to their sneak attack die amount, but they can also lower their sneak attack die count by 1 to gain another use, with sneak attack die resetting on a critical hit or long rest.

So a 3rd level rogue could use a trick twice a day for free, but then they could use a 3rd trick and reduce their sneak attack to 1d6. Once they get a critical hit or long rest they get all their sneak attack die back. This would give them a nice give and take play style with crits ramping them back up. A fighter gets to add extra damage to his manuevers, while the rogue has no extra damage, just cc style effects (maybe a bleed trick)

If fighters got manuevers on the base class that would give every class some sort of resource management (though rage is terrible and should also get some love)
