Page Position Bookmarklet
Hello!
Today I have a trio of related javascript bookmarklets for your browser. They allow you to save / restore / clear your position on any web page. It persists across sessions / reboots / page navigations too. It does this by saving the position in your local storage for each path at each domain. This means that you can save your place on multiple pages (even on the same domain!) and they will all be saved until you use the clear bookmark on each page you saved it on or clear your local storage.
I will probably come back and write an upgraded version of these later, but for now they only save one position per page. It would be neat if the saved positions acted like a stack, so you could save multiple positions on each page.
