Excellent!!! Nice work. Unfortunately I'm not in a position to even look at it
I think that a patch that merges this into the gnucash sources would be
excellent. Another test-case that would be nice is some way to merge the
Hierarchy Druid into an existing set of accounts. E.g., add a menu item:
File -> Add New Account Hierarchy
or something like that.. It would pull up the hierarchy druid and let the user
add more accounts to their datafile by merging it in using your new code.
As for whether to combine this with your previous patch.... Sure, go ahead.
You seem to imply that it's only a small change to the existing files.
However, I wont be able to do anything with your existing patch until at least
Tuesday, so unless Linas wants to apply it I wont be able to get to it until at
Linas: Feel free to apply Neil's patch if you have the chance before Monday
Night, otherwise I'll look at it mid-week and try to get it applied.
