Many thanks, that looks fantastic. Went ahead to install but I'm running Linux and for some reason doesn't want to show on my tray. I've message the author, see if this can be solved. Now just missing to convince the relay authors to save the events as text files, otherwise we won't be able to rescue/port the data afterwards. 

 they are saved as jsonl, you can import on coracle, nostrudel. Backup site like https://backup.greenart7c3.com/ 

 Learning lots  of good things today. Thank you!
