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:
It does look beautiful! I didn't mean to discourage anyone from trying it out. I just remember hearing/reading that it is not updated very regularly, but hey, I used an LTS system for way longer than I should have and I was perfectly happy with it. It's not always about having the latest, must updated software. Maybe you want something stable, or something that looks nice and works. To each his own, I say.
I'm also excited about the Cosmic DE! My issue is that I try to not change my system unless I have too, since I use my computer mainly for work and loosing a couple of days setting everything up is more work that it's worth it for me. So I don't know when I'll get a chance to try it out.
I haven't used Zorin. From what I've read about it it's issue right now is that it's not updated very often. I think it's main appeal is that it has similar vibes to Windows, which makes it attractive for people who want to try Linux for the first time, I guess.
The distribution I used when moving to Linux was Mint, which is also a smooth transition from Windows due to its desktop environment. Also based on Ubuntu, but is updated more often. It also works flawlessly (at least in my time with it).
Right now I'm using Pop OS, and I'm quite happy with it, although I am experiencing some freezes since a couple of updates ago...
Thanks for sharing! These look very interesting. I've been looking into Chinese food for a while, but I'm also interested in Japanese and Korean.
My favorite place for Chinese recipes is Chinese Cooking Demystified . The Mapo tofu and Dan Dan noodles recipes are now two of my monthly meals.
