We find it is much faster to create a ticket simply by sending an email to our helpdesk, then editing after it arrives. This not only ensures direct phone calls are in the ticketing system for visibility purposes, it also time-stamps the ticket for time-keeping purposes.

However, at times I would rather my comments were Internal notes. It would be nice to include a flag or tag that will create my note as "Internal" notes.

With our previous ticketing system we could use #INTERNAL and the notes would be added to the ticket as Internal notes.
