Remember order of opened files in session when reopening session

When switching between files via ctrl-tab,
the list of files is ordered by last recently used.
This order is not remembered when closing /reopening the session.
The last used file is displayed, but the other files are sorted alphabetically.

I suggest to store the order of files inside the session,
so that you can continue with the same state that you left the session.
With this feature you have a fast way to find the files you recently worked with.

As an example:
Ctrl-Tab sort order on session start:
a.cpp
b.cpp
c.cpp
d.cpp

sort order just before closing the session :
c.cpp
d.cpp
b.cpp
a.cpp

sort order after reopening the session:
c.cpp
a.cpp
b.cpp
d.cpp

wanted sort order after reopening session:
c.cpp
d.cpp
b.cpp
a.cpp
