A lot of bugs and missing features, but a bright future if done right.

Now that Arc is dead, there is a lot of advanced users that found Arc features invaluable for our work. Side Space is the right answer, no need to use a specific browser, just use your favorite browser and customize it like Arc. The problem is that it is a version 1.0 app and needs lots of work.

I can contribute by alpha/beta testing and providing lots of ideas and input. Contact me if I can be of help to the project.
