Recent reviews
This extension is only semi-useful... It only sporadically works when at team page at sleeper, and it doesn't update advice when I already have changed lineup in another tab (YES, I clicked on "update advice" when an error popped up after trying to submit lineup on sleeper through this addon):

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
