When using Move To on a Tab Island, please show all available Workspaces in the destination list, including the current Workspace. The current Workspace should be visible but disabled/locked (greyed out) so it's clear that moving to the same Workspace isn't possible.

Right now, the current Workspace is not shown in the list. This frequently causes mistakes: I have to count the Workspaces to choose the correct target, and because the current one is missing, the numbering shifts and it's easy to miscount. As a result, I often move a Tab Island to the wrong Workspace by accident.

Expected behavior:

• "Move To" list includes every Workspace.
• Current Workspace is displayed but not selectable (greyed out).
  
  This would reduce errors and make moving Tab Islands between Workspaces more predictable and user-friendly.
