@Paradinight, I use blueimp in CI 3 before and it works great.. I just add it as a third_party and in the library.. I didn't try it to CI 4 but i know its still possible.. for me I dont want too many libraries in the framework to keep it lightweight.. flexibility in framework is more important than storing too many unneccessary builtin libraries.. thats why im not using laravel. We can use laravel's component in CI plus it is lightweight.. best for every developer
