- more work done on editor :
 * extracted command-manager (operations/undo-redo) into a seperate file
 * added visual display of name / position of current selection
 * added visual display of operations/transforms history (minimal stand-in for now but works)
 * failed attempt at custom bindings/ filtering (attempting to use "toFixed" etc in templates fails, looking
for workarounds
removed useless debug message in screen-capture
