I was trying Greasemonkey this evening. It is an interesting platform to change some particular web-pages in the way you like them to display. Thats an interesting application. You can play with any web-page and even display some contents of one web site on another. I tried some famous scripts for gmail. It is good to see how flexible gmail can be with this platform. Although, none of the applications that I was testing were worth keeping, I enjoyed using it. Probably in future, I need arises, I can revert to it for making confortable changes in the frequently visited web-sites.
