Searched but did not find my issue.
after rebooting my Nexus 7 I found that the gallery widget disappeared. I was able to long click where the widget was before and I see the top delete shows up and I'm able to drag it around but I can't see the widget on the home screen. if I try to drag a gallery widget to the page where I had widgets before it says there's no room on the page but I see nothing on that page.
