The Python window in ArcGIS Pro makes me irrationally angry. As a new-ish Pro user, it's one of the reasons I haven't brought myself to fully learn Python.
One thing that makes the Python Window fiddly to use is the placement and sizing of the sections. From my experience, most IDEs have a large prompt section at the top and a small transcript section at the bottom.
For example, PyScripter:

But the Python Window in ArcGIS Pro seems to be the opposite.

I would prefer to have a large area to type in, rather than a large area to read. Could the position and sizing of the prompt and transcript sections be changed by default?
- Large prompt section at the top
- Small transcript section at the bottom
Not to be confused with manually resizing the sections if needed: Vertically resize Python window sections.
Of course, let me know if I've missed something.
