Don't use <label> tags for things that are not labels, add a proper
<title> for the page, add a back link, remove an unnecessary
`inline-block` style for a header, localize dates and field names, ...
The interface could be further improve: proper diffs for long texts,
better separation between fields, ...
The name of the changed field is translated, values are truncated so
descriptions with thousands of character would make this table huge and
impossible to read, dates are localized, and values like arrays and
booleans are displayed properly.
Our manual implementation had a few issues. In particular, it didn't
track changes related to associations, which became more of an issue
when we made investments translatable.
Using audited gives us more functionality while at the same time
simplifies our code. However, it adds one more external dependency to
our project.
The reason for choosing audited over paper trail is audited seems to
make it easier to handle associations.
