Hello good morning , all you need to do is drag the handle , look for dots or line at the bottom right or bottom edge of the code editor , drag it upward to shrink the code code box
secondly Drag the Divider: Hover between the code editor and where the Input/Output tabs should be; a resize cursor (double-headed arrow) might appear. Drag it upwards.
then for the Toggle Views:
Switch from the “Code” tab to the “Parameters” tab within the node settings, then back to “Code.” This often resets the layout.
