Hi! I’ve been really busy and recently got some time, so I decided to take on a project and came back to Defold. It’s been almost half a year, there have been updates and now I don’t understand.  
First of all, why objects are highlighted in blue? Does it have any special meaning other than that they have been “modified”?  
Second, I can only change a gui node’s id the first time I create it. In the video I tried to show this.  
What am I doing wrong?

It looks like you have multiple layouts in your GUI scene. Layouts are used to adjust a gui to different screens, for instance portrait vs landscape or different aspect ratios (very wide screens for instance). Learn more about layouts here:

Thank you very much indeed! After some thought, I realized that it’s easier to just resize the simulation in the code than to create a layout and make objects half-sized.
