Focus is a remarkable addition that enhances the Emacs experience, bringing joy to programmers.

Staring at numerous lines of code for eight hours a day can be quite tedious. While a readable font like Fira Code is often the go-to solution for improving readability, it doesn’t address the need for focus on a specific block of code. That’s where Focus shines—it dims the text outside the function currently highlighted by the cursor, effectively drawing the user’s attention to that particular code block. Try it out and keep calm while watching your code.
