Does what it says; a bit limited in layout.

Provides the basic functionality I was looking for. The “Icons per row” option could be better. You can currently choose “auto,” in which case it will plug as many icons across as will fit in your sidebar, or “1.” No other integers are available. So I have 8 icons total and want 4 icons in 2 rows, but I can’t instruct the widget “Icons per row = 4.” Instead, I had to take the number of px between icons (10), multiply by 3, subtract that from the width of my sidebar (200) to get 170, and divide that by 4 to get 42.5. By setting the icon size to 42 px, I get four to a row. Good thing I can do math.
