What’s new

• Amounts are read with your team's number format (e.g. 12,50)
• Editing a quote keeps its line-item taxes
• New payments start at the amount still due
• Canadian, Australian and New Zealand dollars
• Pickers hide inactive clients and archived projects
• Time on fixed-fee projects keeps the right status
