It has been shown in numerous studies that web bookmarks quickly accumulate and grow out of proportions. Maybe you are even one of those (like me) that gave up bookmarking all together. Now there is a Chrome extension that comes to help – SuperSorter. From the description:
With one click of its button, SuperSorter sorts all of your bookmarks, in all your folders, into alphabetical order. It sorts folders too and if you like it will put the folders at the top of the list above the bookmarks (like in most other browsers).
SuperSorter also deletes empty bookmark folders, deletes duplicate bookmarks in the same folder and merges neighbouring folders with the same name. SuperSorter can also sort bookmarks automatically every few minutes, making it even easier to keep everything tidy.
I just wonder how much of familiarity (if there is such a thing with hundreds to thousands of bookmarks) is lost when the whole bookmark hierarchy gets overhauled. Maybe it just gets more manageable. Based on 329 (as of October 2014) people that liked the extension it must be helpful.
