Favorite grinds to accomplish on the side via mobile?

Basically I have some downtime at work I’d like to take advantage of and maybe pass on to my GIM friends.

One I’ve almost completed is the graceful set. With Canifis having an abnormal spawn rates of marks, park your character in canifis, every time you log in for a minute or two you’re guaranteed to get at least one mark.

Any suggestions? Thanks!
