Flarum has a beautiful editor but due to its design it leaves us with little text editing space and Preview space
I feel that while writing long discussions it is more convenient to have a preview on the right side and text editor on the left side.
Many markdown editors have the same layout and are quite convenient for editing and adding images while having to see the preview simultaneously without having to scroll or click any preview buttons.
I think flarum should have this feature too. Particularly when we maximize the editor we should have a feature/button to have a side by side layout
