Feature Request: Automatic Dual Mode

**Feature Request: **Is it possible to add a feature/setting to TotalFinder whereas TF is set to automatically display tabs in Dual Mode whenever more than one tab is present?

That is, if I have one tab open and I open another tab, TF would automatically jump into Dual Mode. Say 3 tabs are open and 2 are in dual mode. If I close one of the tabs in the Dual Mode, TF would continue in Dual Mode with the remaining 2 tabs. I guess I am asking for a feature where Dual Mode is the default View setting. An option could be provided in Preferences so that the user could disable/enable Dual Mode automatically. I find I am frequently going to the View menu to re-enable Dual Mode.
