Calibre is great for book management. I use Thunderbird for my email/calendar since I’m on Linux and have never even though of changing. Works like a charm and it does everything I need it to.
Other software I use and recommend are:
- Web browser: Firefox
- Image and drawing: GIMP and Inkscapr
- Plain text editing and programming: Neovim
- PDF reader: Okular
- Media player: VLC
- Terminal: Alacritty (main terminal) and Yakuake (to have a terminal that I can easily access and then hide)
I love the icons! Congrats! I’m looking forward to seeing what you come up with for future new communities.
