Love is in the air, especially when it comes to tiny Tableau tips! I am crushing hard on this color picker/save to tray tip (and I hope you do too)!
And why not show your readers some love and help them out by including a help icon? In this particular use case, I've added the icon as an image and am linking to a sample help file online. There are other ways of doing this as well, but this is one I like so that you can update the help file without updating the viz (as long as the link remains the same). Check it out!
