I use MATLAB R2011a on a Linux system. After finalizing a plot in .fig format, I use either 'save as' or 'export' option to save it in a format such as jpg to include in documents. The problem is that once you save in that format, say .png or .jpg, following that even if I simply 'save' the .fig file after further changes, it saves it in the .png or .jpg format previously used and overwrites the .fig file. This I should say is very careless GUI design on MATLAB's part since every time I cannot remember to select he .fig option and I end up losing the editable .fig format. One could easily lose their hard-earned data that way.
Either whenever we simply use 'save', it should save as .fig by default (since it is the most important format) or at least it should not overwrite a filename with another extension. Such simple things can save lot of unnecessary extra work. Is this the case with windows version too? is there a way out of this?.
Also I need to mention the weird key combinations provided in Linux version such a alt+w for copy, etc. instead of the conventional ones. Even though MATLAB is a software mainly used for engineering and research purposes, some importance to design of GUI has to be given.
