The app doesn't allow filtering by letter or by category like LMS, we always display the full list. However, when browsing by category this list doesn't include not categorised entries so they aren't seen in the app.
Some possible solutions are:
- Allow filtering by letter, category, etc. like in LMS.
- Add the not categorised entries to the end of the list of categorised entries.
- Allow viewing only not categorised entries, either by having a new filter option or by adding a new "browse by" specific for the app to display not categorised entries.
