This looks really great, something I could use and would pay for when polished but there's definitely a few issues for me at the moment:

* Why go fullscreen and modal? I want to drag in links from docs, email, other browsers, have it side by side while reading PDFs etc. etc. this stops me from doing any of that

* Please let me change the shortcut! I already have Option-Space bound.

* Let me put the browser window anywhere I want when it's in the single page non-fullscreen mode, don't levitate it to where you think I want it

* Unless I'm missing something the process of opening a page then adding it to a workspace seems to be three clicks - open page, hit + (plus) button, select workspace, select workspace/inbox - need to make this one click, maybe just show the inboxes? This also seems clunky, I'd much rather browse, drag that page to the workspace/inbox, continue browsing and adding further pages, then arrange all the pages in the workspace after i've added all the links. Seems a faster workflow.
