The Github is a mirror of the main QET repository, which is hosted at tuxfamily.org. Upstream repository: https://git.tuxfamily.org/qet/qet.git/
But user can fork it, work on code or translation and send me a PR (pull request) I can validate and push to GIT master.
For the correction of the names of the elements it is advisable to open the .elmt file with a text editor and modify example :
<names>
<name lang="de">Energietechnik</name>
<name lang="fr">Energie</name>
<name lang="ar">طاقة</name>
<name lang="en">Energy</name>
<name lang="cs">Energie</name>
<name lang="pl">Energia</name>
<name lang="es">Energía</name>
<name lang="it">Energia</name>
<name lang="el">Ενέργεια</name>
<name lang="nl">Energie</name>
<name lang="ru">Сантехника</name>
<name lang="da">Energi teknik</name>
</names>
<names>
<name lang="en">3-way motorized valve</name>
<name lang="fr">Vanne 3 Voies</name>
<name lang="ar">صمّام ب 3 مسارات مُحرّك</name>
<name lang="it">Valvola 3vie motorizzata</name>
<name lang="pl">Zawór trójdrożny z napędem</name>
<name lang="es">Válvula motorizada de 3 vías</name>
<name lang="nl">klep motor 3</name>
<name lang="cs">Trojcestný ventil s pohonem</name>
</names>
If you are using the element editor you are rewriting all XML and the patch is unreadable. I do not recommend it.
