It would be useful if I could (before exporting, or in a separate menu) make a quick check for a language and receive a warning if:
- the original starts or ends with a space, and the translation doesn't (or vice versa)
- the original starts or ends with a line break, and the translation doesn't (or vice versa)
- the number of placeholders (% signs, %s) is different in the original than in the translation
The filter would then show the phrases that have issues.
