Moving the menu to the left, and colours

Click the gear at the top right (Appearance and layout).

• Navigation: Top or Left (wide screens only). Left puts every page in a side menu, grouped under Track, Bill, Manage and Settings. The current page has a marker beside it. Collapse it to icons with the button at the bottom, or by double-clicking empty space in the menu.
• Theme Preset picks the accent colour, and Theme Mode is light, dark or follows your computer.

Your colour choice follows your account to other devices. The menu position is saved in this browser only. Phones always keep the bottom bar.
