@tprouvot I had another thought with this one, what if instead of having an option to set the default height, when the user resizes the editor we silently capture the height and write it to local storage?

Let me know which approach sounds better to you 😊

I like the approach but I think it can be disturbing if not explicitly announced.
What if the option is just a toggle to let users if they want to save the last query input height ?
