Hello,
I just finished making a multitask trainer map that is around the skill level of masters league player. It still can help players below masters but it definitely won't be easy. I made this map in the mind of helping Terrans multitask so there is not a zerg/protoss version yet. To finds this map just search, "Multitask Trainer" and it has a picture of a carbot marine.
Here is a gameplay trailer of this map in action:
If you have any questions about the map let me know :D
