Viewing and Fast Processing of Changelists
If you are using Subversion 1.5 or later on the server and in your local working copy, you can take advantage of the extended Merge Info functionality implemented through the Merge Info pane of the Version Control tool window Alt+9, the Repository tab.

This is done by specifying a pair of branches in the repository (source and target), whereupon PyCharm shows only the changelists from the source branch that have been integrated into the target branch.
Additionally, you can specify various filtering options to minimize the number of extraneous changelists.
Finally, integration and managing integration status are also available directly from the Merge Info pane.
