I would like to dialog can drag and set position.

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

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.

I would like to move dialog (because there is some content behind I need to see in order to fill form in dialog).

It would also be great if it could be resizable. If you have an input component inside dialog, you could set width to 100%.

I would like to switch off scrollbars for individual dialogs, thus it would be great to have a scrollable (https://docs.telerik.com/kendo-ui/api/javascript/ui/window/configuration/scrollable) option to control this behavior. This should be also available in the configuration of dialog service.

When using the DialogService (or the PopupService), you must pass either a TemplateRef or a Component class to the content property for it to create.  However, if you have a Component that needs special initialization (i.e. constructor parameters) or that you have already created using a factory, you cannot use that as the content for the DialogService/PopupService.  This feature request is to allow the content parameter to be valid if an existing component instance (already created) is passed.

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