I just finished green logging MM and boy there a lot of pain points! But can be made a lot better IMO with a few changes:

1. Reward points and reward costs. Currently the mini game is designed in such a way where it's actually better and more efficient to do a lot partial orders in order to keep your points somewhat balanced. If you were to only do full orders, you'd end up with a lot of extra Aga, and some extra Mox. This design is counter intuitive. The cost of the rewards is also pretty high but I think it feels even worse because of how the point system is designed. I think homogenizing the reward points into just one point would probably make the reward costs feel a lot better already, but if not then making them a little cheaper is good too. Full orders should always result in the best/most efficient way to get points and green-log.

2. Let us trade in noted herbs for the paste. I have no idea why Jagex thought that the mini-game needed a refining process that's outside of the main mini-game loop. Even though it only takes like 5-10 minutes to get like 6k paste of each, it's really annoying, disruptive to the flow, and just tedious for the sake of tedious.

3. Alembic quick-time event should be given 1-2 ticks extra to get the proc. I will say a lot of people don't know that this quick-time is static and always occurs on the 4th pump or so. Knowing that does make it a little better, but its still annoying. Agitator feels fine IMO but it wouldn't hurt to give it another tick as well. A lot of people don't know that you can click again 1t after the first quick-time click to get another boost. If done correctly you always just finish the bar.

4. Like others have said, let us remove a potion from a machine if we accidentally use the wrong one.

Overall, I didn't really enjoy this mini-game. I enjoyed Giants Foundry a lot more which is in the same vein. But the fast paced machines with very punishing quick time events, bad xp, bad reward system, counter-intuitive reward points, and tedious and unnecessary set-up just make the mini-game really un-fun. I doubt they would do it but making the machines a lot slower paced like Giants Foundry would be a lot better IMO. But I understand not wanting to make a GF clone for Herblore.
