In the Welcome to %1 text, the version number is not included. When it is localised in a language with a different word order, it becomes alienated at the very end, like "%1 to welcome" + about.version(). Having it like ("Welcome to %1 %2", name, version) would make it much better. Now I checked the code out, wanting to fix it myself, but did not understand a thing :D. That's why opening the report here.
The "Welcome to %1" message is a part and the version is another. Those information can be used in templates. This is the case here, the template uses those information like this: <h2 style="margin-top: 0px;">{{ about_welcome }} {{about_version}}</h2> But this could be different. So, there is no way to fix this without a huge impact on existing templates.
Thanks for the reply, it's alright then!
