I just released a first version of ColorSpot, a command line DX cluster client written in Python. It adds the following benefits to the default telnet stream:
* displays the DX station's country
* displays the DX station's continent
* displays if the DX station uses LotW
* downloads your LotW QSL file and marks all lines with countries that need to be confirmed (optional)
* displays lines in different colors depending on the continent or band (user configurable)
