Additionally I'd suggest trying the tag panel in a horizontal orientation, such as seen in these GIFs. It allows for generally more tags to be seen and edited, while not taking up much more space in the window than a vertical tag panel and by default dynamically adjusts to being resized.
Thanks Lauren Bacall,
You have me thinking. I am pretty impressed with your GIFs! Not sure how you create those but they are very nice and informative. I have thought about going horizontal, but I often split my screen horizontally and that has stopped me from doing so. If I only worked full screen, it would definitely be the way to go.
