For every project I do, I end up keeping extensive notes: everything from a "to-do" list of tasks not yet completed, to useful reference data (like the X-coordinate of the center of the left and right page between the margins), to a record of typographical decisions so that consistency can be maintained (e.g., "in document Foo, add a thin space to the regular space at the end of each sentence"). I keep these notes using Windows Notepad because it uses such a small proportion of precious system resources (side note: I really need to upgrade my computer). Still, that requires frequent switching between Scribus and Notepad (and this is even less convenient if I have more than one Notepad document open at a time). If I want to use both simultaneously, it also requires extensive resizing, scrolling, and zooming to get everything arranged on the screen.
