Merge Request Details
Click a merge request in the list to open its details panel. On GitLab earlier than 13.2, the activity timeline is not available, so discussions appear in a Discussions tab instead of Events & Discussions.
Changes
By default, the Changes tab shows all changes in the merge request. Use the changes filter dropdown to narrow the diff:
| Filter | Description |
|---|---|
| Unreviewed changes | Changes since the last version you reviewed. |
| Compare versions | Compare two merge request versions to see only what changed between updates. |
| Single commit | Changes introduced by a single commit. |
Right-click files in the tree to mark them as reviewed — the reviewed state is stored locally and persists across sessions. Enable Mark Files as Reviewed Automatically to mark each file as you open it, and Show Reviewed File Count to track your progress. The menu also offers Jump to Source and Show/Hide Diff Preview in Tool Window.
Pipeline Status
For open merge requests, the Info tab shows the latest pipeline's state. Click it to list the pipeline's jobs and open one in GitLab; a trigger job expands to show the jobs of its downstream pipeline. The same state appears next to merge requests in the GitLab Merge Requests tool window list.
Actions
The details panel toolbar offers Approve, Close, Add Yourself, Open in Browser, and Copy Link, plus the following:

Customizing the Layout
Drag a tab to the edge of the panel to split it into a separate column — this lets you view, for example, Changes and Comments side by side. Up to three columns are supported in horizontal layout and two in vertical. The layout is saved automatically and persists across IDE restarts.
