I've been using http://hledger.org/ in the last months and although it is great on the CLI, I think it would be better if a journal could be opened in multiple places, and multiple apps could write and read from it and do different things with the same data.
The first step towards that goal was to make hledger run on the browser and implement a simple app that reads and saves hledger journals from and to remoteStorage.
There are probably some usability issues because I'm a remoteStorage noob, so I took the approach of using it a little like a filesystem, with just named files in a global
/ledger/ directory. Feedback on these practices is wanted.
