+# Open Issues
+
+* AB limits are displayed as p.u.
+    * timestamps would be best
+    * named limits would also be acceptable e.g. first solo, second solo, etc
+* Store playback volume separately for each song (also in session JSON)
+* Playlist mode
+    * automatically play next song when current song ends
+    * playback doesn't stop when jumping to next/previous song
+        * should this be the default anyway?
+* AB list view in Qt GUI is currently not working correctly
+    * selection is not cleared properly when changing songs
+    * sometimes crashes when selecting limits with MIDI controller
+
+# Closed Issues
+
+* Moving AB sliders does not set AB limit. Instead need to save AB limit and then select it to apply
+* Loading session is additive, should clear the state first
+* Songs are displayed as full path, should be file name or ideally title from metadata
+* When switching between songs, AB limit selection is not reset, this means that if the song has only one limit, it is not possible to load it anymore
+* No GUI to control playback speed
+* Add buttons to write current playback position to A or B limit sliders
+* Switching between songs and AB limits does not work properly
+    * AB controller only keeps track of limit index, not current song => when song changes, index is invalid but not properly reset
+* Changing song while playing does not update play/pause button LED on MIDI controller
+* Accept file path as argument to Qt GUI to automatically load session
+* Key mapping in Qt to jump to A
+    * Space bar in principle
+        * Not so easy to do actually, used Super L instead
+* AB repeat toggle in MIDI controller
+
+# Use Cases
+
+## Song/solo practice
+
+On PC:
+
+0. Load session

+2. Select A/B limit
+3. Enable A/B repeat
+3. Set overall volume
+
+On MIDI controller:
+
+* play/pause
+* stop
+* set playback speed
+* next/previous A/B limit
+* jump to limit A
+
+## Set practice
