There is also one more case in launcher, if runtime error happens, clicking on script in a bottom panel, will open IDE and highlight the necessary line (with error).

Before this is deployed, please test dramatically, and provide some beta access to those users who can test it in real environment. Many attempts of using VSCode/Claudie with Editor, so far were not possible due to bugs and issues.
