Woah, cutting and pasting a URL dug up a cute little gem: Paste and Go. There's even a keyboard shortcut for that. I can feel myself being more productive already.
Sadly, for some crazy installed on lab computers reason, I lost the fact that this copy was registered and it looks like I'll have to reregister it every time. Hmm, must look into this further.
I like the fact that each tab has its own close button.
Trying to make this whole thing into a blog entry is a mess.. the blogger.com page for posting loads all wrong and the buttons don't work. The little BlogThis popup seems to work okay though. I did a Report this site thing, so maybe it'll get fixed, considering blogger.com is used by a lot of people.
I discovered that you can open a new link in a new page (Opera's term for a tab), and you can also open it and have it load in the background, which is the behavior that I always want. I usually browse a page, and open interesting links for looking at after I'm finished with the current page.
Searching a page for text was kind of disappointing. One of my favorite features of Firefox is that the page search was integrated into the bottom of the window, which reduced clutter and meant that nothing was covered up by the search window.
I've also decided that I like the fact that the navigation bar (with the reload, stop, address bar and google search) is below the tabs names. Visually, it links the navigation bar with each tab individually, which is more appropriate than other browser's behavior which has the tabs as the lowest bar before the page.
