The title pretty much says it all-- I'm trying to get myself onto open source, or at least freely available, software. I've been using WinEdt forever, and despite its faults, it has one killer feature that I can't seem to go without: the way it handles projects.
I'm sure I am not using it exactly as it was intended: I teach several classes, and I like to save all of the quizzes/exams/syllabi/etc. for each class in its own project file. That way, when I switch from thinking about class A to thinking about class B, I can switch projects and have all of my tex files from class B open up at the same time. WinEdt handles this perfectly by saving all the open files as a project and storing recently used projects in a drop-down menu.
Are there any other LaTeX editors that save projects similarly?
