Tested it. Moved back to Brave. Wish I can hide the url field on chrome based browsers. This is the only thing that I like in Arc.

In my view the problem with Arc is the UX. It is hidden and complex and as a result lacks a natural discovery flow.

It seems targeted towards the small audience of specialists which will have no problem giving a lot of their data.

And I hate the size of the borders:) Make them small or remove them completely.
