In addition to files and OnlyOffice, Nextcloud offers many other apps that can be used to create calendars, to-do lists or chat rooms, for example. In general, we are cautious about installing additional apps because we do not want to increase the complexity of the platform any further. However, since many users Nextcloud Decks and the Nextcloud calendar requested, we have installed them. However, the two apps are only activated for those groups and projects that have explicitly requested this. We would like a Pay-As-You-Like contribution of €5 per app from you (see "01. Voluntary contribution payment"). If you also need one of the two apps (or even both), then write us an email at support@wechange.de
You can also send us your requests for more Nextcloud apps, but we cannot promise that we can fulfill them.
