What's the most “well-crafted” piece of software you use?

Things 3, it's a joy to use. I wish there were a mail app of similar quality!

Other than Things, the native Apple Notes app is great. It's simple, fast, and works with a fuss. Sync also seems reliable enough for me.

I like SumatraPDF. Runs the circles in terms of performance around the sad piece of crap that Adobe PDF Reader has become.

Vue Js ( https://vuejs.org/ ) Fast, reliable, and good attention to detail. Amazing execution by Evan (https://twitter.com/youyuxi)

Not now, but:

1. Delphi 2. OptiPerl (Check its screenshots https://www.uptiv.com/free/optiperl/ )

I like pocket app

Possibly, TeX.

KDE Plasma
