Wish for a "Trackheader show/hide" function including a user-definable shortcut key-command. The trackheader is the largest fixed component in the arrange-window. Once set up, tracks can often be identified by their region-names and/or their colour. The user might at times instead prefer to have a quick, free window for overview or precise editing. The Inspector can be toggled showing channel-strip setting, name and instrument for the selected track. A 'thin bar' to the left in the arrange-window, present at all times could be there to indicate used or empty tracks in trackhead-hide mode, toggled with a single key-stroke. The popular MacBook models, in particular the 13" model with it's limited screen-size would benefit greatly from such a function. With more and more editing being done directly in the arrange-window it makes sense to add an option to quickly enlarge the arrange-window for good overview or really zoomed-in editing, utilizing new features implemented in this window. Thereby making the Logic software more adapted for the plenty of laptop users. A toggle-trackheader is in my opinion consistent with the rest of the one-window philosophy and would make it's design more flexible for more Logic users.
