Previewing animation render progress. Different Timeline editors?

Hello. I'm not a great Blender connoisseur but, as I can see, in Blender, the Timeline editor it is the same editor to animate, rendering and for video editing. I mean that all of those proceedings are using the same and unique Timeline. This circunstance, it makes impossible to make an preview of my animation rendering progress, because when i am rendering, the render uses the timeline, and even though I can load the rendered frames in VSE, i can not play it because the render it is using the timeline.

I think that should have different timelines editors, or some way to play the rendered frames progress directly in Blender without to have to leave to another software.

Thanks a lot. Regards!!
