Our workspaces (persistent windows with names) remember your tabs automatically, are multiuser/collaborative, and even have a URL (like any good web object). You can also access your workspaces on multiple computers, so you can start a project at work and finish it at home.
We're officially launching out of beta next month, but you can sign up now if you're interested:
For example, I need multiple spaces where each space is "dedicated" to a single Google account -- it has multiple tabs open that are logged into that particular Google account.
I tried to create that setup, but the accounts "leak" between spaces: logging into a Google account in one space doesn't allow tabs in other spaces to be logged into a different Google account.
If you ever implement proper account isolation per space, please notify me: I'd like to be a beta tester.
Could you sign in to chrome in your different google accounts, with an instance of workona per google account? It's not perfect, but might do what you want it to do?
As another person suggested, you can use Chrome profiles with Workona installed on each, but that likely isn't what you're after.
For example, if I'm halfway through filling out a form but switch workspaces, will it lose my progress? Can I have multiple workspaces open in different windows?
By default Workona opens workspaces in the same window, but you can command-click (Mac) or control-click (Windows) to open a workspace in a new window.
