The "text" view of the parsed FIX messages in hermes v1.13 and others is most useful when there's a need to copy and paste FIX messages into emails, for example. It would be even more useful if you could order, space, and line-break the display. Example of a current display:

ROYB -> PORT: BeginString<8>=FIX.4.2 BodyLength<9>=286 MsgSeqNum<34>=48 MsgType<35>=8<ExecutionReport>
    PossDupFlag<43>=N<ORIGINAL_TRANSMISSION> SenderCompID<49>=ROYB SendingTime<52>=20080516-10:22:52.217
    TargetCompID<56>=PORT TargetSubID<57>=ws OnBehalfOfCompID<115>=ODDOC DeliverToCompID<128>=JPMF
    Account<1>=A1 AvgPx<6>=20.520000 ClOrdID<11>=5435002 CumQty<14>=50 Currency<15>=EUR
    ExecID<17>=OS119f1404f0d-000 ExecTransType<20>=1<CANCEL> IDSource<22>=4<ISIN_NUMBER>
    LastMkt<30>=PA LastPx<31>=0 LastShares<32>=0 OrderID<37>=OS119f13286f9-000 OrderQty<38>=200
    OrdStatus<39>=1<PARTIALLY_FILLED> OrdType<40>=2<LIMIT> Price<44>=20.520000 SecurityID<48>=FR0000133308
    Side<54>=1<BUY> Symbol<55>=FTE.PA TimeInForce<59>=0<DAY> TransactTime<60>=20080516-10:22:52
    LeavesQty<151>=150 CheckSum<10>=021

Here is how I would change it:

a) TargetCompID<56>=PORT becomes TargetCompID <56> = PORT (note the spaces)
b) Tags and values are one each for every line
c) Tags remain sorted numerically small to large, within header, body, trailer of the message.

Is this something you can / would do?
