New writing room interface feedback. Can the legacy editor be made a permanent option?

I want to add to this.

The new editor really does not feel like ready for release.
The first round we got it forced upon us, we actually had to ask you to set the legacy editor as default, since we had breaking bugs in the new one (the legacy slices could not be added and tabs design could not handle more than a couple of tabs before it screwed the entire page).

For a second time, we are forced to use the new editor. The breaking bugs from last time are gone, so this is good at least.
Since I get the feeling that the legacy editor is living on borrowed time, Im trying to use the new as much as possible to get used to it. When teaching our editors how to use the writing room it is now in the new version. This makes the following limitations worse, because it is hard enough to get our editors to understand one version of the writing room.
To have to tell them "To do this, you have to go into the Legacy editor", which looks completely different is not feasible.

Some limitations:

  1. It is not possible to add hyperlinks to images in the Rich Text fields.

  2. It is not possible to scale up images larger than their original size. Yes, it would be better if the editors uploaded a image of the correct size, but it is inconvenient to have to tell them.

  3. Missing version history.

  4. Legacy slices icons are missing. I guess you dont want to put your energy on keeping this alive, but I can tell you it could take years before we will be able to transition away from this.

  5. I find this thread that has been active since 2020, and I really hope the new Rich Text editor will enable you to add new features, because right now this feels like a step back. For example I had one editor that needed help finding the formatting options, as it was not intuitive that one had to write "/" or mark the text to trigger the overlay.

  6. Slugs. Yes, I know these has been deprecated for a while now. But I guess what Im missing is a heads up before the slug suddenly is replaced with a "-" when saving a document in the new writing room. This created breaking bugs for us.

  7. Poor documentation / guides for the content managers. I can only find this. The rest is still guides for Legacy? Or am I missing something?
