Conflict: order of names
Most countries use [first name] [last name] in that order. But there are some other countries where [last name] [first name] order is the official order. Luckily, Familyseach gives us the option the specify, how this name should appear on the tree. That is a really nice feature, however, at the same time it also creates a conflict.
CONFLICT: Many older users prefer to keep it simple and keep the English way [first][last] so their complete tree remains consistent, especially when their tree grows over multiple country borders. Imagine such tree, where certain branches are shown with names [first][last] then other branches appear as [last][first].
On the other hand we all understand that newer users are more than happy to use that nice feature and therefore each name they set in the locally legal, approriate and true naming order such as [last][first]. One such example is Hungarian language.
SUGGESTION: allow users to have an option to show names in a preferred order. This way each user could manually override, how they prefer to see the names, regardless what country setting was set for each name.
To make it simple, I would just say, if you use the English version of Familysearch, this option means [first][last]. If you use the Hungarian version of Familysearch, this option means [last][first]. To be honest, maybe such setting should be ticked in as a default for everyone, while also allowing to untick this option as needed. In this case, unticking this option would result to show each name as per the language setting of the name itself (like as it is happening now).
According to Wikipedia, the [last][first] name order is also called Eastern Naming Order, primarily used in East Asian cultural sphere (China, Japan, Korea and Vietnam), as well as in Cambodia, and southern and northeastern parts of India. It is also used in Central Europe by Hungarians.
