a new feature was just added into AMOS translator filter. Regular expressions can be used now for advanced searching. This allows to filter strings according to criteria like "the string ends with a dot". Most notably, this can be used to detect some syntax errors in the translations. See the discussion at MDL-25667. Thanks to Antonio Espinosa for his contribution.
As a part of this change, the case-sensitivity of the substring search can be now selected. So you can find all strings containing "moodle" (with lower-case "m") for example.
