The graphical user interface is governed by a number of options and defaults. This includes colors, window sizes, axes sizes, default status of checkmenus etc.
During a session, windows can be moved and resized at will. They can be closed and reopened keeping their sizes and positions. (If you, however, close a window using the window manager, it will be reopened in its default size and position.)
Select Save preferences from the Ident window Options menu to save the current window layout and checkmenu status. Next time ident is opened it will use this layout and status. Select Default preferences from the Options menu to return to the default.
The information is stored in idprefs.mat. By default this is stored in the same directory as your startup.m file. Use the command midprefs in the MATLAB command window to select onother directory for this file.
Advanced use: The many options in the plot windows - as well as the default color ordering of the object icons and curves - are all defined in the M-file idlayout.m. To customize these defaults, edit a copy of this file and place it in a directory in your MATLABPATH, before the regular ident directory.
