Display currency is more of a global setting (About You section), and iirc the Australian sandbox example should already be using AUD there(?)
When you add a new account or cash-flow priority for super contributions, the choices should have subtitles distinguishing Concessional from Non-Concessional. But sounds like there are some other places it would be helpful to show those subtitles too?
Always happy to tweak/update the sandbox examples based on what folks would like to see. Any good data sources you'd recommend for more typical UK expense figures?
