Sometimes I need to open an old project, and mostly I remember how it works (i.e. the structure, the formatting and so on) but sometimes not.
At other times I open a project composed by a colleague of mine and it is hard to understand how the project was conceived.
Is it possible to insert in the project a non-printable note to help to understand the project more quickly?
edit: I use QGIS 1.8 (2.0 soon) on windows 7
