1. Button to pick up last used babies with one click on next stage babies selection.
2. Ability to place pills on monsters. Both, on own spawned/friendly, and on enemies.
3. A way to see pills name on hover while on the ground, IF player already tried one and knows the effect.
4. 4 baby slots are fine, School Bag is good, but 1 more extra slot with some sacrifice mechanic would be useful. (like with Poop achievement, player would need to do some continuous actions to get this 1 slot)
5. Keys binding change ability and keys for pills slots(say z-x-c-v by default)
6. PHD item lower price or buff, say each pill can be used twice.
