-Add SOLO functionality alongside the existing audible/mute layer. Control via shortcuts, track editor, or track list widget
+Add SOLO functionality alongside the existing audible/mute layer. Control via shortcuts, track editor, or track-list widget
 New function to create a new empty block from an existing one, that has reserved duration same as the original one.
 Add more time signatures to the quick-insert dialog: 8/4, three variants of 7/8, two variants of 5/4 and more. Also reorder and better labels.
+Add context menu to move CC Blocks to start or end of a track
 Fix splitting of notes that were created by a previous split.
 Block Mode: Fix invisible block labels and graphics when dragging blocks (adopting to unannounced Qt regressions once again)
 Barlines more visible
 Undo for initial metrical instruction and key sig (track editor)
 Prevent block operations to jump to the cursor position in the GUI. Less jumpy.
+Show first block name in track-list widget
 Various small fixes, like typos in variable names and wrong string quotes. Small things can crash as well.
 Lilypond:
   Add transposition of the whole score to properties and metadata dialog
