You can customize your experience with Power-user and save your preferences in the Settings. The Settings can be opened from the very left of the Power-user ribbon, or from the backstage.

Settings for Power-user in general

• Prompt for updates at startup: this setting lets you activate or deactivate updates prompts. We recommend keeping these prompts active so you can keep your Power-user license up to date, and benefit from the new features and bug fixes we release periodically.
• Enable Power-user specific keyboard shortcuts: activate or deactivate Power-user keyboard shorctuts. 
• Save Power-user libraries in: by default, custom libraries are saved in Documents\My Power-user files\. However you can change where these files should be saved by clicking the "..." button on the right and browsing for another folder. This can be typically useful in some organizations that do not allow saving anything in Documents for instance.
• Open temporary files folder: this will open the folder on your computer where temporary files such as logs or previews will be saved before they get deleted.
• Optional libraries: on top of the main libraries of templates, icons, maps, etc., you can also download optional libraries. 
  • The Modern theme of icons
  • The Islands maps
• Power-user display language: switch the language of Power-user. Available languages include:
  • English
  • French
  • Spanish
  • German

• Logs Level: adjust the depth of the logs recorded locally on your machine. Logs allow technical diagnosis in case of some issues. More detailed logs mean more information for troubleshooting, but can also slow down the system.
  

Settings for PowerPoint

• Power-user is the default tab: this will make PowerPoint open on the Power-user tab, and this tab will also be shown by default every time a new shape is created, so you can easily format it.
• Automatically hide secondary buttons from the ribbon when the screen resolution isi insufficient to display all buttons: because there is not infinite space on the ribbon, the number of buttons that can be seen on the Power-user ribbon is limited and depends on the size and resolution of your screen. This setting means that if the resolution is not sufficient to show all the buttons, Power-user will hide buttons that can be found elsewhere in PowerPoint (for instance, the buttons to go to the Slide Master View or Slide Sorter View). The alternative to this behavior is to have buttons grouped, requiring an extra click to access any button under the group.
• Show PowerPoint hints at startup: when this is checked, Power-user will show hint notifications when the application is launched, so you can gradually learn about some features, discover new keyboard shortcuts, etc.
• Open Tab Explorer at startup: when this is checked, PowerPoint will always open with the Tab Explorer active.
• In Tab Explorer, use one line per application: when this is checked, all windows listed in the Tab Explorer will be displayed application by application, with a line break for each application.
• Open Library at startup: when this is check, Power-user will always open with the Library active.
• Show Organize toolbar when similar shapes are selected: when this option is ON, Power-user will show a minimized version of the Organize feature dynamically next to your shapes, so you can instantly reorganize them in a number of rows and columns.
• Disable F1 shortcut: the F1 shortcut in M365 opens a help page. Because some users find that they often press this key by mistake, the shortcut can be disabled via Power-user.
• Sticky notes insertion position: choose between inserting Sticky notes in the inside or outside corner of the slide.
• Start Screen Behavior: Power-user can overide the M365 Start Screen setting, so that when your organization has defined a theme/template to load by default for their users, the same users land directly on that template. This setting allows users to restore the M365 Start Screen setting as an exception to the organization's behavior.

Settings for Excel

• Show Excel hints at startup: when this is checked, Power-user will show hint notifications when the application is launched, so you can gradually learn about some features, discover new keyboard shortcuts, etc.
• Load intellisense to show tooltips in Advanced Functions: unchecking this will stop loading the Intellisense module. This module is used to show tooltips with arguments and a function description when users are typing an advanced function. In some rare cases, it can cause issues in Excel, so this setting will allow users in that situation to disable it.
• Open Tab Explorer at startup: when this is checked, Excel will always open with the Tab Explorer active.
• In Tab Explorer, use one line per application: when this is checked, all windows listed in the Tab Explorer will be displayed application by application, with a line break for each application.
• Open Library at startup: when this is check, Power-user will always open with the Library active.
• Disable F1 shortcut (changes will apply after restart): this allow users to remove the annoying F1 shortcut that opens a help webpage. Because the F2 key is very important in Excel for entering into a cell and editing a formula, the F1 shortcut can often be pressed by mistake, so it can be convenient to disable it.
