One of my biggest gripes about the Notes 8 client was the fact that they'd removed the bookmark bar and replaced it with the "start-menu wannabe", the Open Menu. I figured that eventually I'd work out how to get my bar back but in the meantime I was too busy to bother hunting.
This morning, while trying to find a different feature, I noticed an option called "Dock the Open List" under the View Menu. I clicked it and my faithful bookmark bar returned.
This is so simple and so usable that I figured it was worth sharing. It made my week.
