feat(custom_workspace_ids)

Additional Notes

Current Problems:

• Only works for workspaces 1 - 10, anything higher will fallback to integer index
• There's some user facing string in the settings menu for each workspace id, it has some string interpolation so i wasn't sure of the best way to translate it
