  * User created vector layers may have many thousands of features.  During editing, it will be more efficient to frequently re-render a sketch layer with a subset of features involved in editing.
  * Users will want to edit features associated with raster layers (e.g. a WMS layer with an associated WFS feature type, or a XYZ layer paired with a RESTful feature service).
+ * A single control may work on touch and non-touch devices, but the optimal touch editing workflow will likely require a dedicated control.
 
 ## Controls
 
 ### `ol.control.Select`
 
-(Could also be named `ol.control.SelectFeature` or the plural.)  When active, this control allows users to select features by clicking or dragging (select in a box).  Should allow addition to the current selection (shift-click, shift-drag), removal from the current selection (alt-click, alt-drag), and clearing of the current selection (click or drag outside a feature).  Selected features are (generally) rendered with a different style than unselected features.

 When activated, the control creates a new vector layer.  This layer should have a property (e.g. `temp`) that indicates that it is temporary (so it will not be shown in things like a layer switcher).
 
-When the user clicks or drags, the control calls `readFeatures` on all configured layers (see below for `readFeatures` discussion).  The provided callbacks will be called with selected features (per layer).
+When the user clicks or drags, the control calls `readFeatures` on all configured layers' sources (see below for `readFeatures` discussion).  The provided callbacks will be called with selected features (per layer).
 
 For configured vector layers with selected features, the control calls `setRenderIntent('hidden', features)`.  This signals to the layer that it should be re-rendered without the selected features.
