If I open the comment bar, leave it open until I close it. Why would you think you need to decide when to close a toolbar? If I open it, and close Adobe, I expect it to be visible when I open Adobe the next time. I expect it to be open until I specifically close it. Why would I want to constantly open the only menu I use for 99.99999999% of my menu use in Adobe? And update the time and date on dynamic stamps when I select to insert them again with the "K" keyboard shortcut.
