Hi Ján, hi list First of all, thanks for your great job! And sorry for my poor english Today, we use Agendav (www.agendav.org) for our users. I follow your work since the first release. We need features before migrate from Agendav to CaldavZap in a near future. Maybe it's already in your roadmap? (if not, can you give us your point of view? I read that you work first on the performance issues) - Agendav allow users to share their own calendar(s) directly to other users present in the davical server database. We like this feature because the davical admin frontend is too complex for basic users. - Is-there a way to let the user to choose the color of his calendars. Usefull for groups: each member can select the color of his choice for the team calendar. This feature is not server-dependant (i know that the color can be transmitted to the caldav server but this is not what we want) - Permit users to include external calendars ( .ics ) directly via caldavzap web frontend. Actually it seems possible only via config files. - Permit users to create calendars (already discussed in caldavzap mailing list). I think that it's already in the roadmap. - Forced Refresh button without waiting. ( F5 disconnect the user) Regards; Adrien
