currently you can not switch the layout from right to left.
I guess its doable as the presentation is completely separated from the model.
For translating metasfresh you need to:
1. mark your language as system language
2. run add translation element process
( 3. go to ad_elements_trl and translate the elements into your language )
4. run synchronize terminology to inherit the elements into the fields
@metas-ts is 4. still needed after the last element refactoring?
