Add filters in activities #4806
Description
Currently, the LibreSign app displays all activities together without any filtering options. This can make it difficult for users to navigate or find specific types of actions, especially as the number of activities grows.
I’d like to add filtering by activity type in the LibreSign app, similar to the approach used in the Files app (e.g., "Favorites", "File changes") and the Calendar app, which offers more detailed filtering. The idea is to separate LibreSign-specific filters instead of grouping everything into one generic feed.
An alternative would be to leave all activities grouped as they are now, or to rely on search alone, but this would not provide the same level of usability as having clear filter options.
Additional context
This change would improve the user experience by making the activity feed more organized and easier to use. It would also align LibreSign with UX patterns already established in other core Nextcloud apps.
