12. A non-transitory computer-readable medium including instructions stored thereon, which when executed by a processor of a computer system, cause the computer system to: display, in a unified user interface for a cloud-based collaboration environment, a view in a discussion forum with integrated commenting and task assignment feature; receive, via the unified user interface, a first input including a comment regarding a work item stored in a particular workspace of a plurality of workspaces of the cloud-based collaboration environment; display, via the unified user interface, the comment based on the received first input, the displayed comment including a first option to convert the comment into an actionable event, wherein the first option includes a displayed list of one or more assignable tasks; receive a second input, via the unified user interface, including a selection of a first assigned task from the one or more assignable tasks; convert the comment, based on the first and second inputs, into a first actionable event associated with the work item, the first actionable event including the selected first assigned task to be performed on the work item; display, via the unified user interface, a second option to delegate the first assigned task to a collaborator of the cloud-based collaboration environment, wherein the second option includes a displayed list of one or more collaborators that have access to the particular workspace in which the work item is stored; receive a third input, via the unified user interface, including a selection of a first collaborator, from the one or more collaborators with access to the particular workspace, to which to delegate the first assigned task; assign, based on the third input, the first assigned task to be performed on the work item by the selected first collaborator, wherein a status of the first collaborator's performance of the first assigned task is tracked and updated by a server computer operating as part of the cloud-based collaboration environment; detect a second actionable event associated with the work item, the second actionable event including a second assigned task delegated to be performed on the work item by a second collaborator; in response to determining that the first assigned task must be performed on the work item before the second assigned task, automatically: provide access to the work item, via the unified user interface, to the first collaborator before providing access to the second collaborator; track the status of the first collaborator's performance of the first assigned task on the work item; and display an indication of the tracked status of the first collaborator's performance of the first assigned task on the work item in the same unified user interface through which the comment regarding the work item was received; and in response to detecting, based on tracking the status of the first assigned task, that the first assigned task has been completed by the first collaborator, automatically provide access to the work item, via the unified user interface, to the second collaborator.
16. The non-transitory computer-readable medium of claim 12 , wherein, the status of the first collaborator's performance of the first assigned task on the work item is based on an update on the status received from the first collaborator via the unified user interface.
