save links

I think it would be useful if all links that I attach to my lessons were saved in a part of my lesson planner--perhaps a tab "Links" so that I have all the internet links that use throughout the year saved in one spot (saving online educational games that I find, videos, etc.). This would be so nice so that when I am looking for resources I have used, they are all saved in one direct spot (rather than looking through each lesson for those links!)
