I usually use evernote widget for fast note taking or searching.
Moreover, notes can contain private information, so I don't want any note contents to be displayed in widget.
I chose to turn off "Show Notes in Widget / iMessage", but the "Recently viewed notes will appear here" area showed up.
I think this area looks ugly.
The area in the widget screen is important asset: unnecessary area of one widget can hide part of another widget and it requires (otherwise unnecessary) user scroll when s/he attempts to use this widget, which obstructs fast full-filling of the user need.
