1. Import transactions directly from the Bank website using AqBanking
and OFX Direct Connect.
I'm interested in this too. I was able to download ofx account info with some python script. But currently, I manually
download the bank's csv export and then convert that.
There is no facility for doing this automatically builtin to Ledger.
2. Use transaction names to Auto-complete account names.
The Emacs mode, ledger-mode, can do this.
To be precise, it completes account names. I think ledger entry selects appropriate accounts & amounts based on the
transaction description ? hledger's new add command does something similar.
