Wappler 4 interface question

Lat time I used Wappler was version 3.9
Now I upgraded to version 4 and it seems that you are not able to have the API panel open on the left and a webpage on the right with its properties panel at the same time?
Opening an API item fills the whole screen, which is on a 38" wide screen monitor not ideal.
Is there perhaps a setting to change this behaviour?
