Ux specific to Classic

[magnusbilling]

Hello,

I'm upgrade my App from extjs5 to Extjs6 classic, end sencha touch to Extjs 6 modern

But I have extension on /app/ux that only work with classic, for example:

Ext.define('Ext.ux.button.Locale', {
extend : 'Ext.button.Split',

button.Split is not available to modern.

How I can save it?

Best regards
