This is really handy feature to run trial balances from working copy (file system) and official reports directly from git storage
Ok, then the penny dropped - I can see how that is useful.
I like how all the pta programs seem to complement each other. I take the opportunity to cast my vote for Interoperability!
On another note, I see pdf reports are mentioned. I guess they could be used for generating invoices, would be a useful feature.
