Help manual suggestion

[Pedro Albuquerque]

Hi,

I've been translating the help manual and noticed something.

In the Transactions section, Inserting/Adding a transaction (both single
and multi-split), there is a description on how GC attempts to fill the
account name in alphabetical order.
That description uses the default account separator ":" (colon). But if
someone chooses another character, the description becomes invalid.

In pt_PT translation, I added a small <note> bringing this to the user's
attention.

Regards,
Pedro.
