[TYPO3-calendar] Cal 1.4.0 / typo3 4.5.2 / Events viewable only for a given Fe-User

[Pierre Nya]

Hi folks,

1)is it possible to enter an event that is only viewable for a selected user 
or a group?
2) For which purpose do we need the register "Options" in the FE-Edit? I 
cannot enter sthg there.

Best regards
