There are a lot of addons that do similar things yet all of them are somehow different. In this case... the bookmarking system is actually a core feature of the addon. I do understand that it's not perfect but there's no perfect solution. Perfect it's an individual preference and as a developer it's impossible for me to target everything. And I think that's fine, each of us will look for that we think fits better our needs.

That being said, I'm sorry that you consider the bookmarking system a not so good fit for this, but sadly it's a core feature of the product and it's impossible to change. If I would do that ever it will definitely be a different addon. I believe that that Sync-ing with Dropbox or other solutions might be another good feature but at the same time without offering a cross-browser solution it can be quite pointless. Why there's no Chrome port of this addon. Simply because I don't have time to write it. I have so many features waiting on the list to be implemented into this addon, but at the same time the Chrome version is not so important for me as a developer. This addon was built for Firefox and I continue to do so as a thanks for the Mozilla community. It's for Firefox and I don't think I really want to provide a Chrome version because I don't want to promote a different browser. And of course... competing with Session Buddy is quite pointless at this moment. That doesn't mean I won't do this ever but for the moment I clearly have no motivation to do so.

Ultimately, the addon can't be perfect for everyone, but it can be almost perfect for those that find it useful as it is. Thanks for considering using it.
