In the DIAdem interface, there are menubar buttons available that allow the user to "Save ___ As...", whether it's a script, SUD, layout, etc. In the script editor, there is also a "Save All" button that saves all of the opened scripts. However, 9 times out of 10 I just want to save the current layout/script/whatever. It would be great to have a standard "Save" button either in addition to or in place of the "Save As..." button in the menubar.
(Yes, I know I can use the keyboard shortcut "Ctrl+S" or click "File --> Save" but these options are not as readily apparent as the "Save As..." or "Save All" icons, so I find myself clicking one of those and then having to click several more times just to get out of it...when all I wanted was a one-click save.)
An added benefit would be (like in the Script editor), if the file has not changed then the "Save" icon could be grayed out. That way the user would know that the current state of the current script/layout/etc was saved to disk.
