Hey guys, I'm Arthur and I developed Toby. The motivation behind Toby was basically to have a UI where I could see all my tabs, organize them, have them "on my face" and treat them as stickers or cards that I could drag around and search through. I think that's the user experience that works for me, it's been helping me a lot and has made me more productive, so I wanted to share with other people who might benefit from it as well:)<p>Answering your questions here:<p>- About difference between this and bookmarks: well, it all depends on how you use Toby. I've seen people use it as an actual tabs manager, adding and deleting tabs after they're done with it; others using it as a personal to do management board; and others using it as a bookmarking tool. In any case, I think having that type of UI is the biggest benefit and being able to drag around brings a totally different user experience, which I personally prefer. But please let me know how I can improve it even further.<p>- About Firefox and Opera: I haven't planned that yet, to be honest, since it's a fairly new project and I'm gathering everyone's feedback, but it would certainly be nice to consider that and expand browser support.<p>- About syncing: It's actually already under development and almost done. I'd say I'm 95% done and just need a few tweaks and extra testing before publishing sync with the new release. Yesterday and today we got thousands of new people using Toby and excited about it, so I want to make sure I do it right. I'm sure it's gonna be a super cool new feature.<p>Thank you guys for trying it out and please let me know if you have any other feedback, ideas, comments, etc.
