New Changelist dialog
Use this dialog to create a new changelist.
Type the name of the new changelist.
Type optional comment. When the new changelist will be submitted to the repository, this comment will appear in the Comment text area of the Commit Changes dialog.
Select this checkbox to have PyCharm automatically give the active status to the new changelist immediately after the changes are restored in it.
When this checkbox is cleared, the current active changelist remains active.
Select this checkbox to have PyCharm preserve the context of the task associated with the new changelist on its deactivation and restore the context when the changelist becomes active.
See Manage tasks and contexts for details.
