From 989c0f4f0319f7d8e573c8a88fe8011bd3315466 Mon Sep 17 00:00:00 2001 From: Ramil Nurmanov Date: Fri, 5 Jun 2026 00:06:12 +0400 Subject: Allow grouping by a separate criterion Add an explicit group role to Dolphin views so items can be grouped independently from the active sort role. Previously, Dolphin's grouped view always used the current sort role as the grouping criterion. This meant that grouping and sorting were tied together, for example grouping by type also required sorting by type. This change adds a separate Group By menu. It replaces the previous Show in Groups toggle and allows the user to disable grouping, keep the old Same as Sort behavior, or explicitly group by a selected criterion. When an explicit group role is set, the model keeps groups stable and uses the normal sort role as a secondary key inside each group. The roles updater also receives the active group role, so roles used only for grouping are still updated correctly.
