Here is an update for the tools I’m using. The previous record was in 2013.
MacBook Pro 13” 2016 instead of MacBook Air 13” 2012, two external monitors - one through HDMI, second through UGREEN USB to VGA External Video Card Graphic Adapter.
As main editor I use IntelliJ IDEA, because I participate in Scala and Java projects and for everyday Python projects, because of the debug possiblities.
nvALT for notes I replaced with Write
Alfred to launch apps and workflows as before
Karabiner to map CapsLock to a language switch
SourceTree - GUI for Git and Mercurial
Tomato One to overcome the procrastination
