I actually found a chrome extension to do the job, it's called LivePage
The good thing is that it isn't even related to aptana or another IDE, it simply checks for file changes and refreshes the page. :)
Question
Is there any way to use the live preview ( side-by-side preview ) in an external window/external browser?
I want to be able to have the code on one monitor and the Live preview on another, but if I open the preview directly in Chrome, it doesn't auto-update, and if I use the side-by-side preview I can not open it in a different window.
Maybe there is some chrome extension to make the auto-updates done in Aptana's live preview?
