This is an option that applies to the calculation of the active board. If this option is checked,
TM, at each calculation, will endeavour to recover any white space that develops between
bars on a row by moving bars as left as possible. Recoverable white space can exist, for
example, to the left of a process that is backward scheduled and would thus normally
occupy its JIT position. Having this option on will force such processes to be moved left as
far as possible (whilst still preserving remaining constraints such as predecessors and any
milestone dates).
