Easier custom reporting (maybe Lua)?

[Julien Cornebise]

That sounds like a great compromise solution! The slight lag wrt memory
state isn't a huge problem, at least for the use cases I have in mind.
Plus, saving thé file would sync.

Anyone on this list scheme-fluent and with time and interest?
John, could you point to the part of the codebase that currently calls
gnc-fq-helper , as a starting point, please?
