Realtime Composoting and Video Editing

Blender has an AMAZING compositor and video editor, but it's not real time. We understand that the more effects we add the slower any compositor or editor would get but I think blender is a little too slow. Just adding a simple effect like lens flare or vignette takes some time to composite whereas softwares like Resolve or After effects can do it instantly. And not only can they apply the effect to the frame instantly but they can also playback the animation in real time. I think blender should have this feature/upgrade introduced, it's the only reason why i choose to use other compositors like fusion.

Another cool feature blender blender can have is merging the video editor and compositing workspaces, not literally, but in a way that you can edit your footage and add the effects from the compositor simultaneously, basically something like Davinci Resolve. Maybe there is a way to do this that I might not know of, but i think not.

I would be so so happy if blender would be able to do these things. Doing so will prevent artists from moving between different softwares and make it easier to work in blender.
