emailing with linked fields (templates)

is it only me or the templates really does not work well?

I was able to embedded the account name

but there is no way to include case information in an email?

It is sad because this would be such a productive addition…

Would anyone have a valid list of fields that does work with templates?

I am running 7.7.8 but will upgrate to 7.8.5 lts within 2 weeks…
