The inventor app web user interface makes it very easy to write an app and it is works great. I can write a program in no time, and I am very thankful for that.
After programming some I experienced that a table to place blocks in the block editor would be more easy to overview the written program. So collapsing an expanding of blocks would be more useful, a specially for larger programs. Maybe you have your reasons to not do that... I just let you know guys!
