I work for a client which inputs objects with large amounts of attributes into a large dataset. As of now the attribute editor panel just shows a big list of fields/aliases which can only be highlighted. Most of these attributes could however be categorized (e.g. General, Measurements, Maintenance etc.). A categorization (adding simple titles to groups of attributes) would allow for a clearer overview, faster input and just a general quality of life improvement. The ‘Fields’ tab in the layer properties menu currently shows an interface that would work just fine when applied to the attribute editor panel.
