Accidental Tab Deletion

So I am enjoying the tool and its togglable elements. However, I am frequently finding myself victim of a self imposed injury when a stray click deletes a tab without confirmation.

The same thing happens with toggle-content blocks, but those delete buttons are not housed inside of the target area needed to select them.

The shorter the tab text the easier it is to accidentally delete the tab when trying to select it for modification or display.

I know that popping up a dialog box to confirm whether or not to delete a block is a little heavy handed. But I was wondering it would be possible to some other type of passive validation before deleting a content block.

Something as simple as requiring a double click instead of a single click on the X button, or holding shift to make the delete buttons appear. Anyways, thanks for the great product, here is to hoping we make the world a better place!
