Hi. I just got a nexus 6. I was on iPhone before. I know how to add available widgets, but can we get/buy additional widgets from the play store? I can't find a widget section in the play store and if I Google it, it takes me to a page in the play store that looks like a widget section/category, but when u click on various ones they are apps, not widgets. Are we really just limited to the apps that come on the phone? Sorry if this is newbie -ish. I'm googling and learning.
