I've implemented some new cosmetic features. The in-game desktop actually looks like somewhat like a real desktop now -- it has various icons for (presumably) other applications, as well as a rudimentary NPC-controlled cursor to make it clear when different programs are being started. There is also a nice "shut down" button in the corner to quit the game if you so desire. The latest version of Ren'Py, 6.13.0, seems to fix the time recognition bug I described previously.
