Hey, MT. The grid tool is a nice find. In general, I think I draw more guide lines than anything else.
Have you tried the "projections and guide tools" extension? I find it pretty useful. The "guide by division" tool allows you to create a centered guide between 2 lines - I use that a lot. Beats hunting for the midline snap point. And guides at intervals does 1/2 of what the grid tool does (only one dimension) but allows setting the interval distance. edit: it's not marked as compatible with 2015 but seems to work just fine.
