A new look for iPhone - The bar along the bottom now uses Apple's Liquid Glass design, with Today, Work, Money and Routes. It shrinks out of the way while you scroll and comes back when you scroll up. - Search has its own button on the right of the tab bar. Tap it and start typing to find any client, project, quote, invoice or task. - Ask OneTool and the + button now sit just above the tabs. On a quote or invoice, that spot holds the record's main actions, such as Send or Record payment. - Work is now where you browse your records by type. Searching moved to the new Search button.
