I strongly suggest implementing a side-by-side UI for the 'Code View' and 'Block Editor' rather than the current dialog-based Code View. Currently, it is a challenging task to figure out the exact/matching line number in Code View to correct any HTML tags.
The proposed enhancement would allow users to seamlessly view and compare code modifications in real-time within the Block Editor, providing a more intuitive and efficient editing experience. Please note, that the current placement of the Code View dialog restricts the user from viewing the block editor. (A sample given as attachment)
