Additional Button options for Widget Controller

[JeffreyThompson2]

Related to my previous idea but different enough to warrant its own post. The buttons in the Widget Controller should have a few more options. The largest button size is still pretty small (1.34 rem) (and the small is unusably tiny). I would love a few Extra-Large options. I could easily see using sizes up to 2 rem. 

Also, using borders/box-shadows on the buttons looks very nice and really helps them stand out when used directly on a map.
