Better path when saving plots

[massimo ceraolo]

I keep the directory in which I keep my source files distinct from the OM working folders. The latter, in fact, is filled with many files (c files, object files, mat files, etc.). For instance today it contains 5454 elements.

I think this distinction is good practice, and therefore maybe a lot of other users do something similar.

When I save a plot, however, OMEdit always prompts the default OMEdit directory as a first choice, even during the same session. So when one has to save several files, he has to navigate through file directories continuously.

I suggest that OMEdit keeps trace (during the same session) of the last directory used for saving plots, that it can prompt when a new plot is to be saved
