I was working on one of my sites still hosted with Yola, one that has a lot of images, css, and js files. I remember reading from an employee somewhere that the file manager will index files for 1 hour, or something along those lines. I would love it if there was an option on the file manager that says "Clear Cache" and it will clear the last index. That way we have the option to have the files refresh immediately. But then again, this is just a thought.
