Do you miss the Jaguar Favorites folder? I added my ~/Library/Favorites folder to my sidebar and found it still has nice heart icon. I use it to store my servers, and I also added the folder to dock so when the servers are connected, I can browse through them by right-clicking my MightyMouse.
[kirkmc adds: For some reason the Favorites folder still exists in Tiger, even though there is no GUI access to it. When Panther came out, and no longer used the Favorites folder, it also removed the keyboard shortcut that added aliases to it (Command-T, which now adds items to the Sidebar). However, my Favorites folder contains aliases created post-Tiger, so there must be some keyboard shortcut that I hit accidentally from time to time that sends aliases there. It is odd that this folder still displays, in the Sidebar, with a custom icon, but that is probably for backwards compatibility; when you upgraded to Panther, the Favorites folder appeared, by default, in the Sidebar.]
