-  the backend is unreachable.
+  From here, users can create new events, edit or delete their own events, leave
+  invited events, or view detailed event information.
+- **Event Management:** Fully featured event management allows users to create,
+  edit, and delete events. Events support color selection from a color picker,
+  detailed descriptions, and attendee invitations. Invited events are integrated
+  into the calendar, and invite notifications provide quick actions for managing
+  responses.
+- **Category Management:** Users can create, edit, and delete event categories.
+  These categories can be assigned to events to organize them effectively.
+  Categories also support color selection for easy identification.
+- **User Authentication:** Secure and robust authentication with automatic
+  login for valid session tokens. Tokens are securely stored & persist across app
+  restarts, allowing users to access the app without needing to reauthenticate
+  every time they open it. Registration and login are straightforward, and access
+  tokens are refreshed automatically to maintain session continuity. Once a
+  refresh token expires, the user is automatically logged out and redirected to
+  the login screen.
+- **Invitations and Notifications:** Users can invite others to events, and
+  invitations appear as notifications. Invite notifications contain support
+  actions like marking as read, previewing the event details, accepting or
+  declining the invitation, and deleting the notification. When an invitation
+  is accepted or declined, the inviter receives a notification update, letting
+  them know about the acceptance/rejection.
+- **Error Handling and API Base URL Management:** When the app cannot connect
+  to the API server, a dedicated error screen is displayed. From this screen,
+  users can modify the API base URL, allowing seamless switching to another
+  server if needed. This Base URL setting is also accessible from the login and
+  register screens.
+- **Settings and Account Management:** The settings screen is accessible to
+  logged in users and offers comprehensive account management. Users can update
+  their username, email, and password, delete their account, or log out. The API
+  base URL can also be adjusted from here.
+- **Event Details View:** A detailed view displays complete event information,
+  including its creation date, description, attendees, categories, and, if
+  applicable, the event owner's details for invited events. This page offers a
+  full view of the event, unlike the event cards shown in the day view, which
+  only show a summary.
+- **Color-Coded Visuals:** Both events and categories support color
+  customization via a built-in color picker, making it easy to differentiate and
+  organize items visually.
+- **Clean and Intuitive UI:** The app's design prioritizes usability and
+  clarity, with features like the event-based day highlights in the monthly view
+  and a simple card format for daily events. All functionalities are accessible
+  through logically organized pages and actions.
+- **Notifications System:** The notification page supports the previously
+  described invite notifications, but also general message notifications, which
+  the administrator can send (currently only possible by directly adding it to
+  the database, as the API doesn't support privileged/admin accounts, though
+  this would be possible to add in the future). Note that the app doesn't
+  support push notifications, so notifications are only visible from the
+  notifications screen when the app is open, however, this could be implemented
+  in the future as well.
