Link it!!! We've got 2 accounts and 2 credit cards all linked it's amazing.
The sections I have (after 6 months - might give it a rejig soon) are:
Non negotiable monthly direct debits eg mortgage, council tax, energy
Things we could cancel monthly direct debits eg Spotify, Disney plus, cleaner
Non negotiable relatively fixed annual savings pots for car insurance, car tax, MOT, house insurance,
Annual pots for birthdays, Christmas
Regular Savings including serious grown up savings but also fun 'targets' eg lion king tickets at the moment
Longer term saving pots eg home maintenance, emergencies, holidays
Kids eg clubs, hobbies, clothes, holiday clubs
Normal spending eg petrol, main shop, top up shops, coal / logs, homewares
Fun spending eg eating out, entertainment
Roughly in the order I need to fund them so I start at the top and work my way down to allocate salary but then start at the bottom and work my way up to cover overspending.
I love love love YNAB but just start using it and you can adjust constantly until you've got something right for you.
It took me months of forgotten expenses until I had anything like a comprehensive list of exactly what our money goes to.
