This time I actually did not install the OS, but I am writing this from running live image from USB disk of Zorin OS Core. Running Wide Open Thoughts was easy, I had to install g++ and OpenCL, but otherwise smooth as it should be. Default text editor highlights C++ code nicely (see below).
Installing Google Chrome from Firefox was easy, no need to touch the command line. Settings are nice. GIMP was already there, LibreOffice as well.
Didn't notice a single problem.
