I have plenty of custom functions that I’ve written for my WordPress website, and currently, they’re all in the functions.php file of my theme. However, as the number of functions grows, I’m wondering if it’s better to split them up into separate plugins, rather than having them all in one file.

Are there any advantages to creating separate plugins for each set of custom functions? Would it make my website run faster or make it easier to maintain in the long run? Or is it fine to have them all in one file?

I’d appreciate any advice on the best way to handle this situation. Thanks!
