"Take each H1 heading and split that section off into a separate document tab"

A simple but tedious task that I wanted to do for a large document. Nope, Gemini says it can't do that. It offered to tell me HOW to do it though!

Is there something Gemini can actually do that's useful?

I did something similar after copy/pasting Markdown into a Google Doc, assuming Gemini could obviously convert the section headers and such…nope!

combined with separate plans to use the Gemini CLI, it’s an incredibly goofy situation

I asked Gemini to create a chart from the tabular data I had, and nope, it can't do that.
