Navigation +
Navigation + provides Mode plugins so that developers can create modes that take over the Navigation sidebar.
Edit mode
Navigation + provides Edit mode. When a user enters Edit mode the Navigation sidebar is replaced with a Photoshop like toolbar. Edit Mode is the foundation of the Plus Suite. It provides a Tool plugin manager so that other modules can provide tools like Layout Builder+ and Edit+. The goal is remove the need for Edit and Layout tabs to create content. The Plus suite enables in place editing.
Hotkeys
You can change tools with hotkeys. Hover over the tool in the sidebar. It will show a tooltip with the hotkey for the tool. Hold Command + Shift to show all Tool Indicators regardless of what tool is selected.
