This is already after the data capture part. The hard part is to remember every little transaction I had until I have vim at my hand. The only solution seems to be working more or less is to take out my phone and type it as soon as the transaction happened. And I won't try to use vim on phone ever again..

Most of the time, there's no need to remember. Just put the receipt in your pocket, and when you get home you can further postpone it by stacking it with other receipts on a receipt spike. It's only the cash transactions that are best not left postponed for longer than a day or 2, but if you just scribble down the important bits on a scrap of paper, you can postpone it like any other receipt.
This is one of the reasons I use YNAB (for shared household budget) and a Google sheet (for personal budget).
I usually just hold onto the receipt for whatever I do until the end of the working day and get it entered that night. But if a receipt or my pay app isn't an option then I can enter the transaction right there on the phone before I forget.
I use GnuCash. For card transactions I simply import my bank statement .csv file every other week or so. For cash transaction, I use the app on my phone, otherwise I just forget how much I spent and where, by the time I get to my PC.
I never really got past the importing stage in GNUcash. I want to categorize the payments into different accounts, depending on how the money was spent. But there is no easy way of doing it. Or doing it iteratively.
When you import all your new transactions are presented. You can click (or ctrl-click to choose several) and match them to an account of your choosing.
It also memorises what transactions go into what category, so after you categorise, say "PURCHASE LIDL" as Expenses.Groceries, it will automatically match future transactions with the same name to groceries as well.
