I ask after reading your vacation write-up. Seems like the input side could have been a lot easier if you had a speech or text NLP interface to ledger. "$10 entertainment expense paid from MasterCard today," for example. That could be the holy grail for people who are not inclined to keep a detailed ledger, or for situations where input is difficult. (Theoretically you could email/iMessage/SMS/slack that string and have it picked up by your ledger file.)
