Wish: Additional options for command line operations

I miss some command line options for batch usage:

- [ ] run minimized / run hidden. Useful if utilized as background data fetching task i.e. in Ecxel etc.
- [ ] define fields to written into the output file. Current output depends on stored preferences. If used as background data fetcher, changed preferences would cripple i.e. the output of the calling Excel macros.
