Safari is probably the most used app in macOS. Fortunately, with the upgrade to macOS Catalina, Safari gets some useful new features. Here's a look.
The home page has a new way to help you get to sites you want to visit. It still shows Favorites and Frequently visited sites as in previous versions, but now there is a Siri Suggestions section which shows recently visited sites, Reading lists links, iCloud tabs, links sent to you via Messages and more.

Move Window Left / Right on Screen
Under the Window menu, there are two new options: Tile window to the left of the screen, and tile window to the right of the screen. These help sort the Safari windows.
When you select one of these options, the active Safari window moves left or right on the screen (depending on which option you selected), and tiles on the other open windows appear on the opposite side.
If you click on the large webpage, Safari expands to record the entire screen. Press the Escape button on the keyboard to exit full-screen mode.
Clicking one of the tiled windows expands to fill the rest of the space next to the active active window.
