[Feature Request] Options to customize

[stfnx]

Out of all the workspace indicatur plugins I found this one to be my favorite. However I think there is room to improve. Sadly this extension is not customizable at all.

I'd wish the following options:

• Only show used workspaces (where a window is opened)
• Customize foreground and background color of active/inactive/empty workspace

I'd like to suggest one more customization option: show workspace full name for only the current workspace, while only the initial letter for others.
