Position tabs vertical - only in explorer view

First I want to congratulate you with the new Opus 12! It's great.

I want to display the tabbar vertically, only when in explorer view.
When using two panes side by side I want to display the tabbar at the bottom.
Is this possible?

In preferences I can change the position of the tabbar but that effects all my listers.

At the moment there's only the central Preferences setting and it isn't possible to override it in individual windows or styles.

We could add a command to change the Prefs setting fairly easily, but that would only really solve things if you only use one window at a time (or multiple windows but always in the same style as each other).

Making the tab bar position independent in each window isn't a bad idea, but might need some extra thought on our side to work out how to implement it, and how to configure it + how the setting would interact with styles, layouts, etc..

Thank you Leo
