Thats nice and all, but Im a Chromium user who wants to manually audit and edit my \User Data\Default\Local Storage. That wasnt a problem in sqlite days, tons of tools available. Switch to leveldb not only made that difficult (one paid GUI tool in existence afaik), but also introduced a change in localstorage behavior. Chrome localStorage used to return entries sorted by key, this is no longer the case.
I believe Chrome has deprecated LevelDB at this point. It turns out that LevelDB doesn't work well when you need many different databases in a single application. So all new Chrome storage is SQLite. At least until they find something better...
