Settings-Languages Page Better Interface Design

Good day from Canada!
I have been fighting with the translation of AppText in many languages.
May I propose a slight modification of the interface (see screen capture).
I have used Export and Import CSVs and that works fine.

However, when I need to add one App text or verify an App text in many languages, I end up having to scroll up and down every time I am changing languages.
Improvement 1: Make the scrolling area over the actual list of App Text fixed, therefore we would always have direct access to the menu (Create Text, Export / Import, Language Selector.

Improvement 2: Add a Search text field. Makes it easier to find a text in the list.

Those two small improvements and simple design changes would save a lot of time!
