+===== (Multi) Session Handling =====
+\\
+\\
+Can multi-session handling work reliably ? \\
+Is it too complicated ? \\
+Can a single-session be open multiple times ? \\
+\\
+The current behavior, to me, feels strange and unexpected:
+Opening a running session (twice) opens another set of windows.
+What's that ? Do I have a "doubled" session now ?
+It is very opaque, unclear, which window belongs to which session.
+Is that how it should be, is that what we'd want ?
+\\
+\\
+An idea:\\
+Add a sessionID. \\
+The client would allow selecting the session it belongs to (with a drop-down-box). This would allow multiple sessions to be open.
+Every session should have an associated color (light, water-color) and a short description string (user-assigned), the applications can use to visualize dependency to a particular session.\\
+\\
+For example I could have a "light-green" session with hydrogen and qsynth and a "light-orange" session with audacity and lv2host running at the same time. \\
+\\
+In qjackctl, there would be an option "create new session" with a dialog, where I would be able to select a color, enter a string, for a new session.
+\\
+\\
+**Store connections:**
+\\
+  * Every saved sessions stores all connections currently active (when hitting save).
+\\
+**Restoration of connections** in a multi-session environment.
+\\
+  * Start with no connections, nothing connected (keep existing connections ? rather not - they could conflict ?)
+  * Load first session    => connections of __applications belonging to__ that particular session __are restored__ (only)
+  * Load a second session => the same
+  * __Restore additionally__ saved connections __if the user requests__, from an already loaded session.
+\\
+Every app has a drop-down-box, where one of the loaded sessions can be selected, i.o. to become a member.

 ===== Comments and additional ideas =====

   * Qjackctl - sesssion: save, works as 'save as' now. It would be nice if it would be possible to have also the opportunity to hit just 'save'.
