Hello Smalltalkers, I'm currently working on new code editing tools, and I've implemented a new subclass of PluggableTextMorph named PluggableTextMorphWithLimits , with a code oriented feature: You have a warningLimit ( 350 by default ) and an alertLimit ( 2* warningLimit by default ), and the number of characters of the text displayed is counted ( without space, tabs, cr etc). If you are below the warning limit, the background is white ( or the default color ), if you are between warningLimit and alertLimit, the background turn more and more yellow, and if you are above the alertLimit, the background turn orange :) After using it for ten minutes, you start shivering when the background turn yellow ;) Gofer new squeaksource: 'Nautilus'; package: 'PluggableTextMorphWithLimits'; load. You can test it by evaluating: PluggableTextMorphWithLimits example. I think it will be used by Nautilus, but maybe more code editing tools should used it. Thanks in advance for your feedback :) Ben
