Since the last update 2018.07, the window of the playlist can no longer be reduced arbitrarily.
This is very annoying for me. I use sonar on a laptop for live music. In the playlist I have over 200 projects.
I have set the playlist window very narrow and adjusted each project window next to it.
Now the playlist window in the narrowest setting obscures all projects because it occupies 1/3 of the screen area.
How can I narrow the playlist window again?

Thank you

Hi Rabukel. You can deselect the columns that are displayed and the playlist will narrow to a certain degree, but you are quite correct - the playlist behaviour has changed and you can no longer adjust it as you could in the past. I can understand your frustration. I previously used Sonar for live performance and had a very specific screenset that involved a narrow playlist.
 
FWIW I now use a program called midi automator which provides enhanced playlist functionality in any DAW.
