Nothing..
What editor do you use for developement?
HomeSite 4.5 is the best windows Perl editor if you ask me.
You can set the tabs to spaces, (how ever many you want, 3 or 4 is what I use) that way your code always looks clean regardless of the editor you view it in.
Some editors treat tabs different than others so using spaces is the best :)
Oh and nothing beats HomeSite's syntax highlighting :)
Ever consider putting your code in a CVS and giving reged users read privis? :)
