Identified - This OX Cloud platform update includes the following main features: \- Categories from a searchable dropdown: Type to filter the list, or type a new name to create a category and apply it in one step. The same picker assigns categories to mails, appointments, contacts and tasks, and filters searches by category. \- Sortable mail search results: Search results can now be sorted and ordered like a normal folder, by sender, subject or size rather than only by date. Cancelling the search restores the folder's own sort order. \- Settings and notifications as side panels: The settings menu and notifications now open in a side panel instead of a floating popover, with keyboard focus moving into the panel as it opens and returning to the button that opened it on close. Calendar reminders and invitations offer a “Show in calendar” link that highlights the appointment in the current view. \- This release introduces support for Brand Indicators for Message Identification (BIMI). BIMI lets mailbox providers display a verified company logo next to incoming messages. In the OX App Suite UI, the BIMI logo is resolved and rendered locally so we can offer a preview in the compose dialogue and enrich list views. Fixes to the OX Cloud platform in this release include: \- <https://documentation.open-xchange.com/appsuite/releases/8.52/> Expected Impact: \- No user impact is expected.
