This feature is a mark that shows clearly where the cursor is when you are working in WordPress Gutenberg. This feature I am requesting was a part og WordPress earlier, but has been removed. This was very useful because it shows clearly which block is active. Today it is much harder to be sure which block you are editing and much worse which block you are deleting. You have to click several times in the editor to make sure you are editing the right block. This is such a useful feature. Why was it removed? Please bring it back.
