Animation Graph editor

it would be helpful if you can manipulate your keyframes with graph editor. I tried to edit save file by my self. no help.
we really need this to create fancy transitions. I am waiting for this for every release. I saw roadmap but no mention about graph editor and motion blur.
please watch this video to see what i mean (sorry for my grammer not native english speaker)

The Keyframes panel is already a form of graph editor.

but my friend it is limited. is there anyway i can get more control over this. you can check out enve 2d animation software It also got same graph editor as in after effects. but it don’t have any video editing features.
