When Wisp is installed, the default setup for the notification feed is the floating feed.
The floating feed is placed on one of the bottom corners of your page. It's called 'floating' because as you scroll, the feed stays fixed relative to the window instead of moving with the page.
When the feed is opened, it expands up and toward the middle of the page. The floating feed enables a really simple, out of the box setup to get started with Wisp.
If you want to learn more about editing the floating feed button's appearance, check out the doc 'style the floating feed'.
