Might already be in place and I haven't figured out where.
1) I also use gimp, one of the features I find useful for the side bars is the 'TAB' shortcut key to hide ('Mask' per GIMP) the sidebars to get extra display on screen.
2) Since 'Space' takes you already to the command-line... could the the 'CTRL-M' be a keyboard shortcut to turn the command line on and off. Or alternative keyboard shortcut.
Is this a possible add for v3.x?
