today's major task was working on a couple of help files for the gui. one displays the readme file that comes with the package (which took me perhaps longer than it should have to display properly). the other describes what the buttons on the summary and locus screens do. i played around with using a floating tooltip attached to the mouse, but my understanding of how it worked was not sophisticated enough to make it anything other than annoying. i also added a folder of test data to the package on GitHub. bring on thursday - it's been a good first half of the week!
