Many CQRLOG users thinking about the contest logger from CQRLOG.
IMHO the best native contest logger for linux is console ncurses based TLF (https://github.com/Tlf/tlf). TLF is still alive and developed, the new version is announced for next week. TLF is also integrated to fldigi, xplanet, dx cluster and so on.
Maybe it would be worth to consider any kind of integration cqrlog with tlf? I am not a coder, but this may be easier to do than coding the new contest logger.
Just casual proposal...
