In the Photos app you can hide photos both on the Mac and on iOS. Hidden photos will disappear from Photos view, albums and other views, but they will appear in a special Hidden album. This feature is not meant to be a secure way to protect photos, but just a tool to hide photos before deleting them or to take off photos out of normal viewing methods when they don't belong there.
I recently discovered that when people search the iOS App Store on an iPhone or iPad, they ofter view the typing suggestions as search results. However, these suggestions, which appear automatically, only give you a few established choices. Tapping the Search button to actually execute the search will show you the actual search results, complete with images, descriptions and more.
In addition to adding quick ways to access web sites in Safari bookmarks and the Favorites bar, you can also put links outside of Safari that will launch Safari and go directly to that page. You can add them to the Desktop or any Finder location. You can also put them in the Dock as a single link or a folder of links. You can add them to the Menu Bar with the help of the Script Menu.
In Numbers for iOS there is a special feature that allows you to enter data into form, rather than directly into a table.

If you have trouble reaching the keys on the iPhone virtual keyboard, especially when holding it with one hand, you have the option to use left or right one-handed keyboards. These come in especially handy on the iPhone 6, 7 and 8 Plus models, where the screen is just a bit too wide to reach all of the keys using just your thumb.
You can do a few things to make the keyboard on your iPad easier to type on. You can undock the keyboard from the bottom of the screen and move it to a position that is better for your hands. You can also split the keyboard to place the keys closer to the edges when holding the iPad with two hands. Both of these options are available in vertical or horizontal orientations.

You may want to download third-party (non-Apple) apps for your Mac from time-to-time. When doing so, it is important to keep safety and security in mind. Four rules will help you stay safe when downloading apps: Don't get an app unless you really need it, get it from the Mac App Store if you can, only get an app if you trust it, and only download from the app's official site.
When you print you actually launch a print manager app. This app allows you to see which print jobs are waiting, pause them, and even result them if they have failed while in the middle of printing. You can also use a viewer to see what is being printed.
If you are using the Notes app only to store simple text, then you are missing out on some of its advanced features. You can store images, videos, audio, links, map locations and many other things in Notes. You can also add checklists and tables. Objects stored in notes can be examined and also exported and shared.
You can rename multiple files easily in macOS High Sierra and other recent versions of macOS. The option to do so only appears when you have selected multiple files. You can choose to simply replace text in all filenames. Yo can also add text to the beginning or end of a filename. You can also set up formatted names, such as numbering groups of files.
In Icon View in the Finder, you have several options that are not available in list or column view. You can change the label size and move it to the right side. You can turn on an option to show additional information like image dimensions and how many files are contained in a folder. You can even set the background color of the Finder window to something other than white, or use an image as the background. Many of the same view options are available for the Desktop as well.
You can see which web pages you have open on all of your devices using iCloud Tabs.
