Adding numbers to all strings, or adding source text to all translations
To test the Afrikaans translations, I found it useful to do one or two things to the TS file: 1. add a unique number to each string, so that I can match up a string from the UI to one in the TS file, and 2. add the source text next to the translation in the TS file, so that I can see both in the UI.
Perhaps this might be useful to other translators as well.
The linked-to script is an AutoIt script that processes the TS file in the selected manner.
See the image below for what it looks like in MuseScore when I dared to select both numbers and having the source text next to the target text. (I might not use the numbers option a lot myself unless there is one pesky little string that I just can't figure out its corresponding string in the TS file for.)
