Umbrella leaf fix

I like that in pvz 3 the umbrella leaf has a certain umber of uses because in pvz 1 if you had 4 umbrella leafs on the field half of the roof zombies couldn’t do anything 

But in pvz 3 they didn’t feel that useful so instead some buffs that I think it should be

umbrella leaf could stun the swinging zombies to make it feel more impactful and it can use it’s leaves to knockback zombies that are on the ground by a tile as a form of last line of defense and potential stalling if needed but it uses its leaves in the process 

another idea is the umbrella leaf could deflect the projectiles like the bowling ball back at the zombies to make it feel like it has a use

 Also some bonus questions

will choose your seed slots come back?

is updates planning to happen every month?
