It can't display markdown and formatted code side-by-side which is kind of a surprise.
I haven't tried doing anything super complex with it yet. Just having it generate some poems, but it's smart enough to be able to use natural language to edit the middle of a paragraph of text without rewriting the whole thing, didn't notice any issues with me saying "undo" and having data change in surprising ways, etc. So far so good!
I'm not very skilled at creating good "test" scenarios for this, but I found this to be fun/interesting: https://i.imgur.com/TMhNEcf.png
I had it write some Python code to output a random poem. I then had it write some code to find/replace a word in the poem (sky -> goodbye). I then manually edited each of the input poems to include the word "sky".
I then told it to execute the python code (which causes it to run "Analyzing...") and to show the output on the screen. In doing so, I see output which includes the word replacement of sky->goodbye.
My naive interpretation of this is that I could use this as a makeshift Python IDE at this point?
