Currently there is no easy way to programmatically close a dialog from within the dialog component. Also it should be possible to a return a reason why the dialog was closed which may be different to the action buttons and the reason should be available when subscribing to the result stream 

Perhaps have a look at the ng-bootstrap dialog and implement something similar. See: https://ng-bootstrap.github.io/#/components/modal/api. If the content of the modal is a component, then nb-bootstrap can inject the dialog instance into the dialog component (using the NgbActiveModal class). The NgbActiveModal class can then be used to programmatically close / dismiss the modal from "inside" the component.

I need accessibility  support for dialog, h2 in the title, role=alertdialog on the window

Would like to be able to set the color on the kendo dialog. We have a mobile application that uses dialogs for error reporting and some times informational reporting. Being able to set the color on the Dialog title bar as well as the button color would be a great feature.

The api should allow for the close of dialog on escape or backdrop click.

Currently there is no way to ged rid of 'x' closing button in top right corner. It can be hacked by css globally, but if using the DialogService yoy can not configure if the closing 'x' should be present or not - that would be nice feature

Currently the dialog cannot be opened without placing the dialog in the component template. For some scenarios like confirm dialogs, providing a service that creates the dialog is more convenient.

I would like to dialog can drag and set position.

The main.js file for all modules seem to be kept in the following file structure:
dist/npm/js/main.js

however in the dialog module the main,js file is 
dist/npm/main.js.

This inconsistency causes issues when using systemjs and loading the packages this way.
