Well, I'd hardly call these _great_ ideas, but here they are for what
they are worth:
1) Allow your users to set the default font size for widgets with
an environment variable. I have this bit of code in the startup file
for my application:
; allow the user to customize the default font for widgets
fontsize = getenv( 'IDL_FONT' )
IF strlen( fontsize ) NE 2 THEN def_font = fontsize ELSE $
def_font = 'lucidasans-'+strtrim( fontsize, 2 )
IF def_font EQ "" THEN def_font = 'lucidasans-12'
if !D.NAME eq 'X' then widget_control,default_font=def_font
This lets them choose a point size for the default lucida-sans
font that I prefer, or set a completely different font of thier
own choosing.
2) Map different parts of your interface to the same part of the screen.
Yes, its not always desireable from an aesthetic point of view, but
it can save real estate. A builtin example of this can be seen in the
behaviour of the SLICER or XLOADCT widget.
