Shameless plug on a lightweight (~50 lines of code) Chrome extension I wrote called Tab Extract to attack the too-many-tabs-open problem from another angle:
The ability to reorganize/move tabs between windows helps a lot. I use SessionBuddy and VerticalTabs, plus Alfred's "tabs" search command, but none allow moving tabs to other/new windows.
Tabli has a very nice UI, works well and the code is top notch but no reordering/moving tabs unfortunately.
Another useful extension that doesn't work in recent Chrome versions is TabSplit and so far I haven't found an alternative.(https://chrome.google.com/webstore/detail/tab-split/imjbfepo...)
