I have some translations we are working on, but some saved translations have new line characters (\n) at the end, leaving me with a po file like:

: Views\Course\Lessons.cshtml:271

msgid "Complete final exam"
msgstr "完成期末考試\n"
""

Maybe your editor could automatically trim whitespace from the beginnings and ends? Maybe a setting, incase some people like it?

Very nice tool :)
