Key editor view

Key editor view could include horizontally a lot of lines of information : notes, expression maps, a lot of controlers lines and I hope in the future, marker line (other suggestion !) and so on… Is it possible to include a “button” (in a corner for example) to minimize the view of each line one by one ? With this feature we could have a larger place to view notes which is important when we edit, for example, more than one instrument… Example : if we want to edit simulateoulsy Violins (first and second) , altos, cellos and basses… of a virtual orchestra;… We need a large place to view all notes… We currently have to completely cancel controler lines or expression map lines and reopen it (right clik, selection and cancel + right click selection and reopen). With a “minimize” button for each one, it could be very fair… This suggestion msut be a complement of another one which is the possibility to give a name to a controler (ex : to substitute “controler One anme” by “modulation” or “controler 21” by “vibrato” if it’s the case…
