A Stalwart Selection of Big Spenders is currently beta-testing version 1.2
of XBOOK. This version adds income categories and reporting (much like the
expense categories currently available), grand totals for the category
reports, sequential check cancellation in addition to cancellation by
number, and a few other efficiencies.
Look for it soon (but not quite yet) here. And if you have any specific
features you'd like me to include, now's the time to tell me.
