I've notice that when you enter a certain expense description (eg: 'Aldi'), the UI automatically picks up on it and suggests a certain category (eg: 'Groceries'). This is a very nice feature! But afaik this only happens because 'Aldi' is known and hardcoded.
I've got repetitive expenses at local stores, the application can't possibly know about those in advance; But they are in my history, labelled with a certain category. It'd be cool to have a similar feature to what I just described, but based on my personal history.
Eg: I enter <name of my local bakery>, and because I've linked that to a category before, the UI autofills the category based on whatever I linked it to most recently.
