Building a trading journal what should it have?

I’m working on a trading journal project and wanted real feedback before building it 😅

What features/details do you think a trading journal should have to make it genuinely useful?

Like what things do you want to track for every trade? For example:

Entry & exit

RR ratio

PnL

Setup type

what else?

Swing, intraday, options, scalping all perspectives are welcomed
