Other facilities, such as automatic conversion to systems of units (MKSA, CGS, atomic units, ...) as well as special conversions (temperature/energy, mass/energy ...) are also possible.

Enhancements:
- Improved the missing file notification if Multialias finds items that have moved or are missing.
- Overwriting an existing file when saving is improved (with the always ask option).
