Editor connector tool for workflow continuity among editors + additional features

Hello guys. I would like to propose a feature that would be very useful for blender as a whole but most importantly the image/video editing and compositing area.

The main focus are the tools and features that would be critically helpful for blender to improve as whole. Color grading and color correction is a very typical workflow among all cg creators there is. The task is so necessary and common that you ought to think that it is quite easy to find and access those basic tools and utilities that would help the artist achieve that and move on to the other part of the project. But no, this is not the case. Although there are multiple programs that would help you do that most of them are not free and if there are free they are not that intuitive and some are even too complicated to work with that you end up doing the task longer.

Among all softwares that are present, the only software that stood out to have the greatest potential for this proposal is blender. Coloring pipeline is so in demand that blender would benefit from it significantly. The features it has makes it not impossible and hard to achieve. It is already there and all we need is to utilize the functionalities it has to offer.

In these feature proposal, the following lists are the main concepts the possible future of blender tools.

A. Pipeline connection/continuity among editors in a specific workflow

B. Video sequencer color diagram tools like histogram, vectorscope, and waveforms be available as a node in the compositor

C. Better accessibility for the basic tools and commands that is mostly used in video sequencer. (Ex: Transform widgets for the viewer, mask tools, export media button, etc.)

D. Common tools improvements/changes and how to optimize it for color correction and color grading use.

                                     Video sequencer color diagram tools like histogram, vectorscope, and waveforms be available as a node in the compositor                             

In the sample image above; the viewer node which is in the left most side, is different from the current way of dispalying the backdrop. An alternative viewer which in this case is a node would be great aside from having the regular backdrop. This viewer node can be turned into its original form or its other form which has an image attached to it.

The viewer node can also be scaled accordingly. Putting an image inside a node would make it more easier to move the reference along the viewport spcace.
