Save and Load Sessions / Workspaces

[YeshuaAgapao]

I would like to be able save a 'session' or 'workspace' so I can quickly re-open all my active characters, library files, and template files in one go, such as in the attached screenshot - 6 characters in 5 campaigns, Advantages + Skills + Equip + Spells, Campaign houserule templates

I think on top of that it would be convenient to have GCS be able to open the last or a specific workspace by default (similar to how browsers let you start with the last opened or specific tabs). But saving and loading workspaces would be a nice start.
