A popular request was to have sticky headers for lists in SharePoint 2013. This is very useful if you have long lists with loads of columns. Sometimes the user cant remember what a value in one of those uncountable column stands for and has to scroll all the way up (if there’s no pagination). To help those users I wrote a small script that glues the header right underneath the gray bars on top in case the lists header scrolls out of view.
