1. Replace the edit handle with the corresponding mode icon (eye for VisualEditor, wikitext icon for Source) to better reflect the selected mode

I think in most cases users know which mode their in, in which case the primary function of the tool is to let users know there is a button for switching modes. There may be a better option than the pencil for this but I don't think the eye is an improvement.

3. Improve each menu structure by grouping related items with subtle dividers, making options easier to scan in menus

As a personal preference, I think the full height over/active state looks strange contrasted with the partial height divider:

We would also need to consider other toolbars, such as mobile and the 2010 wikitext editor.

4. Removed the ellipsis from the Publish button (from "Publish changes..." to "Publish changes") since using ellipses at the end of actions is not a good practice, even when the button is loading

Using an ellipsis to indicate that a button will start a process or launch a dialog rather than instantly completing an action is a widely used practice:

In past testing users indicated that they were hesitant to click the publish button, and this is why we went with ">" on mobile to make it clear you were just going to the next step in a process.

The idea was to represent the selected option rather than including a new icon that users need to understand and recognize, since there are already too many icons in the toolbar.

With grouping menu items I meant the dropdown menu displayed by the toolbar options. I think it would be better if we can group them in some way since there are too many options in each menu.

Google chrome	LibreOffice	Firefox

If it helps clarify the action for users, I’m fine keeping the ellipsis, though it may introduce some unnecessary noise.
