Wishlist item/Feature request: exclude buttons, instead of include

[mapsedge]

If I want the default toolbar without a button, the script looks like

		$("#divnotes").trumbowyg({
			btns: [
				['viewHTML'],
				['undo', 'redo'],
				['formatting'],
				['strong', 'em', 'del'],
				['superscript', 'subscript'],
				['link'],
				// ['insertImage'],
				['justifyLeft', 'justifyCenter', 'justifyRight', 'justifyFull'],
				['unorderedList', 'orderedList'],
				['horizontalRule'],
				['removeformat'],
				['fullscreen']
			]
		});

Note the "insertImage" button is commented out or removed. I want everything else in the default. Would love something shorter that excludes a button from the default list, something like:

		$("#divnotes").trumbowyg({
			btns: [
				['-insertImage'],
			]
		});

btns minus insertImage.
