Viewing and Managing Integration Status
With the extended Merge Info functionality, you can view and update changelists' integration status.
Subversion stores the information on whether a changelist has been integrated into the local working copy or not. Based on this data, PhpStorm informs you on the integration status of a specific changelist by displaying one of the following icons next to it:
integration status unknown
To have the integration status displayed, click the Highlight Integrated button on the Merge Info pane toolbar.
You can change the integration status of a changelist without actually integrating it into the working copy or reverting the previous integration. This will affect only the administrative data.
To toggle the integration status of a changelist, do one of the following:
To mark a changelist as Integrated, select it and click the Mark As Merged button on the Merge Info pane toolbar.
To mark a changelist as Not integrated, select it and click the Mark As Not Merged button on the Merge Info pane toolbar.
