   1. If sorting is enabled or the user / extension has supplied extra menu items, show the menu button. Otherwise don't show it.
   1. We'll need a way to separate extension menu items from user menu items so the user doesn't override them.

+UI-Grid allows you to filter rows. Just set the `enableFiltering` flag in your grid options (it is off by default).
+
+Sorting can be disabled at the column level by setting `enableFiltering: false` in the column def. See the last column below for an example.
