1) It is not possible to scroll down to the end of your code when you reached the end of the window. Workaround: Copy your code and paste and extend it to Notepad and copy it back to Qlik Sense.
2) The yellow helpbar is a little bit to much present. Actually it distrubs you more than it will help you. If there is a part of your code behind the yellow bar you can not see it! You start a battle with this bar to see your code! 🙂
Would appreciate if you are going to fix this in a new Qlik Sense version.
Thanks.
