@harriskenny
Thanks for this comprehensive list! This is very useful.
Quick question for you: calibre for e-books is #foss, is it not? May I ask why it's not on your list. Just curious. I'm not pushing it one way or the other.
@mediumchat calibre is only omitted because i wasn't familiar with it 👼
I will add it -- thanks for the tip!
@mediumchat Oh I'm happy to hear that, it's mostly been me emailing myself programs when I see/read about them, it's really grown beyond what I'd anticipated haha
Server run by the main developers of the project 
It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!

Cool! I also picked up a few apps I was not familiar with through your list. Much obliged.
