Eggbun will create a default workspace when you first open it. You can create as many workspaces as you like from the system tray or the workspace menu in any open Eggbun window.
Each workspace:
Each workspace using its own browser profile means you can have two workspace and be logged into separate google accounts. If you work at multiple companies, or have a personal gmail and a work gmail you'd create separate workspaces for them.
Even if you load the same projects in two separate workspaces and they both have a gmail bookmark, you'll be able to use two different sets of credentials.
You can also show/hide all the windows that belong to a workspace from the system tray. This makes it really easy to switch between your side project and your work, or as a contractor switching between clients while being able to have layouts of windows, panes, and tabs remembered across sessions for each one.
In workspace settings you can change the name of each workspace or delete them.
