I was seeing a issue or we cant say it an issue just a suggestion. When we enter some details in code, forum, or blogs section and in the mid of writing the contents, by mistake if i click on any of links in the menu at the top it redirects the page and leaving the datas which we enter useless. So we need to again go to that section and write the data again to post it.
this happen to me twice and this time i see clicking on the back button of the browser the data remains the same. Instead we can make a popup to intimate the user that data entered will be lost when redirected like in gmail when we enter some details and if by mistake we click on any other link instead it will tell that datas are entered and do we need to discard.
Similar way we can make it so that it will be useful for the users to avoid losing the data.
