I use tab suspender with a 10 minute timeout and tree style tabs. It's amazing. I usually have over 100 tabs open, and I can collapse the tree branches I'm not using and only 10 or so tabs will actually be using resources. Performance is night and day compared to before I started using suspender. It's not everything I want though; I too feel the need for something in between a tab and a bookmark and it's frustrating that there aren't any options. I'm considering building one myself but I already have a dozen other projects that are more exciting than browser tab management.
Tab Suspender Doesn't always accurate reload my tab. Another problem is I want may be at least a Jpeg of the Webpage, not a Tab Suspended Web Page notice.
Tree Style Tabs Doesn't work for me, I tried it a number of times, in theory it should, in practice it is a little over complicated. Tab List so far is working great for me. As of writing I have 260 Tabs opened, thanks to CES.
