Turn/off TooManyTabs context menu - For those who prefer a less clutter context menu,please go to options and selected "Disable TMT context Menu".
fresh options for the TMT popup width - whether you open TMT window by keyboard shortcut (e.g. ctrl + ~), now you may go to options and adjust your popup width. Set a larger width whether you would like to see more tabs in the popup.

Note this only applies to windows open by shortcut. The Chrome limitation (width max. 800px) still applies to the standard popup.
Enjoy!
