At the moment, I hadn't planned adding a script interface, but we
might in the future. There's some internal data restructuring that
needs to be done first. I'll comment more on that below.

The issue at stake here is that reports use a data structure that only
has those levels. So, the first step is to restructure the data to
better mimic the category hierarchies. Also, today the reports are
displayed as html, and the code for html generation and data
calculation is mixed together in a big pile of messy code. That has to
be fixed, with data calculation on one side, and report rendering on
the other. With that, we can think of adding a more dynamic mode for
reports, using UI widgets (QTable or similar) instead of static html.
This way, we could have changes to the report on the fly,
collapsing/expanding columns/rows as needed.

This, I don't quite understand. You can have this now. Customize an
income and expense report to show the data monthly, for the dates you
want. The chart detail can be modified independently of the report
(with the above mentioned constraints).
We offer a default array of reports (which we are already being told
as too many :) ), but each report can be further customized in a lot
What are you missing?
What I'd like to have is the ability to drill-down with a click.
That's a mid-term goal. Again, I don't think scripting is the right
way to go, but a good combination of sensible data models and UI

A sample of the customizations would be great. Knowing the gap between
what we have today and what is desired is a very good step. My own
imagination only goes so far.
Feel free to ask any doubts or issues you find.
