Lazy session loading: when restoring browser state from session, only the active tab will be loaded. Remaining tabs will be loaded when activated. Enable here: opera://flags/#lazy-session-loading
Extended lazy session loading: changes mode of operation of lazy session loading so that all tabs are gradually loaded in the background. Enable here: opera://flags/#extended-lazy-session-loading
I use my browser tabs as a to-do/to-read list – bad habit, I know. At any given time I have at least 40 tabs open. For people like me, features such as the above boost browser startup time significantly and help consume less memory.
I use my browser as a reading list as well. And I like it.
I have had epic browser sessions with more than 500 tabs, until I discovered the Max Tabs extension, that let's you set a max limit. I use 100 now.
The extension Bartab Heavy lets you load only current page on start and automatically unloads tabs after x amount time. Otherwise 500 tabs wouldn't be possible.
Furthermore I use Tree Style Tab extension, that put them on the left side. I got used to this in Opera. Still miss the Ctrl + Tab (IIRC) feature, that only showed the list when you tabbed trough them akin to Windows' Alt-Tab window.
The existence of these extensions sooths me a bit since it means I am not the only one with these bad habbits.
Good to see Opera still attracks new users.
[Edit] Pano can also hibernate tabs or groups, so if that's the last thing you're using Bartab for it can replace that as well.

In the mobile world they offer access to their compressing proxy built-in, similar to http://www.khelekore.org/rabbit/ so that you can save your OTA bits. I haven't found any other mobile browser that allows you to push your web connection through a proxy like that.
Note that Opera’s “Off-Road mode” in present in Opera for Desktop as well; it’s not a mobile-only feature. Here’s a screenshot that shows how to enable it: http://i.imgur.com/rvGkQrI.png

I only brought it up because users on Windows and OS X who download more recent versions will be getting a very different, and unfortunately quite inferior, experience.
