Scroll to Idea position in Ideas Listing when going back from Idea
When there is a long list of Ideas and an user click in one idea to see it, going back to the Idea listing page goes to the top of the page. If there is a long list of ideas the user will need to scroll back to where s/he was before clicking in an idea.
It would be interesting to see if the user is coming from an Idea page and if yes, scroll down to the clicked idea position.
