I've released version 0.3.7 of my WIP #Psion Agenda-like app "Pygenda" targeting keyboard-equipped PDAs running Linux (#GeminiPDA, #CosmoCommunicator, #PinePhone + keyboard, #PocketReform, F(x)tec #Pro1X).
The last two releases have been bug-fix releases (two releases because minutes after 0.3.6, I noticed an API change in a dependency was causing a crash & rushed out a fix). Hopefully it's in a good state for testing now.
