на этапе генерации шаблона приложения можно сказать какой тип вам нужен и всё будет выглядеть традиционно. Например так:
sencha app generate -ext -classic MyApp ./MyApp

А где прочитали что это возможно???

Вот читаю справку:

http://docs.sencha.com/cmd/6.x/advan...a_generate_app

Нет тут опции -classic!

sencha generate app

This command generates an empty application given a name and target folder.

The application can be extended using other sencha generate commands (e.g., sencha generate model).

Other application actions are provided in the sencha app category (e.g., sencha app build).

Sencha Cmd can also automatically download and extract a framework by specifying the name of the framework as an argument:





sencha generate app -ext MyAppName ./MyAppPath
This will generate an application using the newest version available for the specified framework.

For Ext JS 6, by default, this application will be a Universal Application. To override this and select a particular toolkit, you can use either of these variations:





sencha generate app -ext -classic MyAppName ./MyAppPath
sencha generate app -ext -modern MyAppName ./MyAppPath
