Ideas for placing tab-specific actions

Question

I've got the following tabbed interface

Each tab is a scrollable list of items that can be marked as checked or not.

You can click on the blue button on the top right to add a new item to the current tab.

If you switch to a different tab, the button label and where the new item will be added will change accordingly.

Now, I've got this new requirement to implement a check/uncheck all items for the current tab. Functionally, it's simple enough, but I'm at a lost as to where to place this functionality.

---

Note:

• Inside the tab, it can only be a list of items. Can't have a menu bar at the very top of the list.
• There is a lot more room between the tab labels and the button than what my crummy mock shows. Enough to fit say two more buttons.

Answer 1

First of all I wouldn't place "Add tab one item" button in the tabs section. For me it looks like you're going to add a new tab. And answering your question - I would place checkbox in the header of the list. You could also use this header for other actions with list.

Answer 2

If it's not possible to place the select-all checkbox inside, a good place for it would be on the left-hand side, aligned with the checkboxes of the items.
