Helo @herbert24. I know that you have created a PR for Widget labels but did you included the changes for Condition alert messages? Code here.
Because there are 2 different situations regarding this talk:
widget translations
conditions popup messages (save, delete, error)
I don’t see the changes on you PR for point 2.
I have made some investigation and I’ve made some changes on coreapps in order for this messages to be on the code properly (through i18n). I will make a PR for this.
