Undecorate unmaximized window

Hello Mate Community,
I am trying to work in a 1280x800 and 1280x720 dual monitor setup with all windows, when I have such scenario set, tiled. But since it is relative small display resolution, some window get unreadable content, because there is the upper decoration, the menus and toolbars along.
If I remove the decoration of this unmaximized windows, it would help to better view the content, and off course using such app’s configuration to hide menus and toolbars.
Could this be achievable in Marco sometime?
