Hi. I just install the new Katalon V5.4.
Averything seems OK but I just cannot find where is the Global Variables button in the upper right of the GUI. A bug or a miss understanding from me???
I have the same problem. Can not find the Global variable editor anywhere…
Found them! Tests Explorer/Profiles - there are your global variables.
Ah! Thanks a LOT Dusan 
Hi all,
It’s been moved to be default profile of Execution Profile: http://docs.katalon.com/pages/viewpage.action?pageId=13697476. Sorry for misleading information here, we will improve it in later versions.
Regards
Merci
