How are Tab Groups superior to using windows for tab groupings?
With Mac OS 10.5 I have been using windows as a defacto method for tab groupings. When tabs get two crowded, I open a new window. I have to move between windows to get to all tabs in a group. The Tab Grouping instructions don't address moving tabs from multiple windows into a single large group, say, for charts on a large number of stocks. [A disadvantage with my multiple window system has been my occasional misstep, e.g., closing a window full of tabs with the red button when I intended to minimize the widow with the yellow button, or, worse, when I get the option after a Firefox crash or power loss to Restore windows and tabs or Start a New Session and I hit the Start New session Button; in either event I lose the tabs and/or windows affected.]
