# Copies and tab groups > Run a widget more than once with separate options, and stack several widgets in one spot with tab groups. ## Copies **My widgets → Add another copy** (or `umbractl add-instance `) runs the same widget a second time. A copy has an id like `sp500#2`, and that id works anywhere a widget id does. Each copy is a separate window with its own: - options (follow the S&P 500 in one and the Nasdaq in the other), - enabled and locked state, position and size, - saved data (`umbra.store`). ```powershell umbractl add-instance sp500 # creates sp500#2 umbractl set sp500#2 symbol ^IXIC umbractl remove-instance sp500#2 # removes the copy and its data ``` The first copy can't be removed, only disabled. Removing an extra copy from the right-click menu offers **Undo** in the tray menu for a short while. ## Tab groups A tab group lets several widgets share one spot on the screen with only one visible at a time. A hover tab strip switches between them, and the visible tab takes over the group's shared position and size. ```powershell umbractl groups # list groups umbractl groups create todo "Work" # a new group, starting from the widget copy "todo" umbractl groups join clock # add a widget copy to a group umbractl groups activate clock # show one umbractl groups next # also: previous umbractl groups cycle 30 # rotate every 30 s (5-3600; off to stop) umbractl groups rename "Focus" umbractl groups icon clock rocket # tab icon: a bundled name, or `default` umbractl groups reorder clock 0 umbractl groups leave clock # remove a widget from its group umbractl groups delete # ungroup; the widgets stay ``` `` is the group id that `umbractl groups` prints. Tab icons come from the widget's own `icon.png` (64×64, light grey on transparent) or from the bundled icon set, which you pick in Settings or with `umbractl groups icon`. Your choice wins over the widget's icon.
