Custom navigations allow teams to focus on the areas of functionality that are most important to them, and they pair well with customized terminology, so your team can work with the language it's used to. You can always re-enable areas in the future as your needs expand.
You can customize your navigation in your product settings. The easiest way to get there is to move your mouse to the top of your Aha! screen and look for the pencil icon next to your profile picture. Click that pencil to move directly to the navigation settings.
You can inherit your product's navigation settings from a product line, or you can select Customize navigation to change the layout for your currently selected product. Check or uncheck boxes to add or remove specific elements of your product's navigation, then click Update at the bottom when you are done.
The layout that you choose will be presented to all users of the product. You can choose different layouts per product or product line or set a customized product line to be inherited to all products and product lines beneath it.
Note: By default, every screen except Features > Workflow and the entire Ideas section are enabled. The Ideas section automatically enables per product as you create ideas portals.
