I like that interface idea. There is ledger-autosync (in Debian and on GitHub[0]), which should pull transactions from with accounts with OFX. I haven't tried it as none of my accounts are reachable through OFX.

If your bank supports OFX/QFX download, you can still use ledger-autosync. You can manually download as many transactions as you like, and it will only import the new ones.
