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.
To use them, simply drag the 2 links below to your bookmarks (bar), and click "Save Inputs" when you wish to save the contents of all the inputs, and click "Restore Inputs" and paste in the code you received from the "Save Inputs" bookmarklet to restore the contents of the input boxes on any given page.
To use it, simply drag the link below to your bookmarks bar and then click the bookmark when you want to use it. After it loads, you can then select the element of the page you want to focus, indicated by the blue border. You can also press 'A' to attempt to autoselect a flash object, while avoiding ads.
