language change issue (again)

There is an issue with changing the language on devices running Oreo:

In Android 8.0 (API level 26), the following methods now use Locale.getDefault(Category.DISPLAY) instead of Locale.getDefault(): Locale.getDisplayScript()

That's why the language changes for some things but the most part of the app doesn't change the language.

small feature request: It would be very helpful if the app give you the possibility of restart the app immediately for the lang change. Maybe with a popup window -> like to restart now? It's not comfortable to do it by hand or go to the advanced options each time you want to change it. And for a better overview of available languages a drop-down menu with all included langs would be also more helpful. The language names are all translated into their native names on Tx but we can use the english names for the selection.
