Hello,

In fact, iCagenda listing is based on dates... so a date is needed.
But, with a custom theme pack, it could be possible to not display any dates in events list.
The only issue is that to order event, without editing core files, it could be possible only by using a date, which could be hidden in the theme pack.

I have plans for the future, to able some extra-possibilities, but to early to speak about, as so much other things to do before (in short, it could be the possibility to have an option to set an event as featured (display at top of the list) with possibility to have no date set... but as said, no real idea of it, and of a possible development...)

Best Regards,
Cyril
