Renaming of buttons on leaving a task

The buttons in translate5 editor, that are available for leaving/finishing a task should be renamed:

DE:

• "zurück zur Aufgabenliste" renamed to "Später weiter arbeiten"
• "Aufgabe abschließen" renamed to "Alles fertig - Aufgabe abschließen"

EN:

• "Return to task list" renamed to "Continue task later"
• "Finish task" renamed to "All done - finish task"

And the dialogue that pops up, when "Finish task" is clicked should be renamed to

DE:

• "Wollen Sie die Aufgabe wirklich abschließen?" renamed to
  "Noch etwas zu tun?
  Doch noch später weiter arbeiten?"

EN: 

• "Do you really want to complete the task?" renamed to
  "Still something to do?
  Better be able to continue later?"

And then the functionality in the pop-up between "Yes" and "No" should be switched, so that "No" finishes the task and "Yes" keeps it as it is.
