Some software makes a distinction between saving and exporting. Lets take the image processing software GIMP as an example. The save button will only allow to save the project file in the native gimp file format .XCF. If one desires to save the current image in any other format like .png, .jpg etc. one has to use the export button. While I understand the obvious difference between saving a project file and exporting a project file I feel like this distinction makes for a very bad user experience. The number of times I clicked "save" when I really wanted to export my work is depressing and I hear the same from colleague.
Are there any benefits to this distinction for the end user over the simple selection of the desired file format in the save dialog?
