These are the ones I use most actively, on my FreedomBox:

• bepasty for moving around or sharing temporary files
• Quassel for staying connected to IRC servers
• Radicale for synchronizing my calendar and tasks.
• Syncthing for files I want to have available between my laptop, desktop, phone.
• Tiny Tiny RSS for following blogs.
