I do have a default word content available for the user, and the user will be able to change the content if required. 

The track change feature would allow reviewers to quickly zoom into the edited wording (i.e. highlighted in red) for them to review quickly.

ADMIN EDIT

If such a feature were to be implemented as part of the component feature set, it is likely to show diff via CSS and HTML elements and would not likely compare against a Word (or any other) document.

For the time being, you can consider a custom button that will do an HTML diff against the original content that was provided to it to show it in the editor, but reconciling any changes will be a more complex task that is very far from trivial to implement.

Currently, the Insert Image Dialog for the editor labels doesn't look great. the first two seem right-aligned and the second two items seem left-aligned. this screenshot is from the demo site.

Please expose the ability to allow additional HTML attributes in the Editor content.

===ADMIN EDIT===

Provide support for:

• custom attributes for the Editor elements
• custom tags

I would like to be able to customize the content of the Iframe in the Editor with CSS.

Telerik edit:

In the meantime, it is possible to inject CSS styles in the Editor <iframe> with JavaScript:

@inject IJSRuntime js

<TelerikEditor @bind-Value="@EditorValue" />

@* Move scripts to separate js files in production. *@
<script suppress-error="BL9992">
    function injectEditorStyleTag() {
        var doc = document.querySelector("iframe").contentWindow.document;
        var head = doc.querySelector("head");
        
        var style = doc.createElement("style");
        style.type = "text/css";
        
        var css = "body { background: #fed; font-size: 24px; }";
        
        style.appendChild(doc.createTextNode(css));
        head.appendChild(style);
    }
</script>

@code {
    private string EditorValue { get; set; } = "<p>The default font-size is 24px.</p>";

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            await js.InvokeVoidAsync("injectEditorStyleTag");
        }
    }
}

I bind the TelerikEditor Value to a property that is reloaded with different unrelated content. The editor keeps the Undo/Redo stack so for the "second" content I can Undo back to the "first" content. I'd like to be able to clear the Undo stack.

I'm trying to use the Blazor editor but the "Insert Image" function is very basic. Previously using Webforms & Core the insert image in the editor presented the user with a file management and image upload popup. Is this functionality available with the Blazor component?

=====ADMIN EDIT=====

Possible alternative:

1. Utilize a custom Editor's tool that opens a Window or Dialog containing a FileManager.
2. Use the FileManager's SelectedItemsChanged event to determine which image the user wants to insert into the Editor.
3. Programmatically execute the Editor's insertImage command.

In fashion similar to the following example for the React editor that's done through the onMount ReactJS-specific event: https://www.telerik.com/kendo-react-ui/components/editor/plugins/#popup-tools

For example, like the AJAX editor where the field appears only when simple text is selected, but when complex content is selected (e.g., other html tags like <strong>, <p>, <img>) the field is not available.

Like other editors from Telerik (say, Kendo, WebForms).

An event that we can hook into so that we can take the (presumably) base64 encoded image (link), upload it somewhere, and then replace it with an image element set to the uploaded imaged file. Ideally, that would work for other content too.
