Hardcoded file paths

This is yet another plugin that is failing because it has filepaths hardcoded in the PHP code rather then correctly reading the paths from the wp-config file. It’s getting quite annoying by now since I’ve been trying to find a decent plugin for about an hour now!

I have no “wp-content” folder, but just a “content” folder instead.
I have no “plugins” folder within a “wp-content” or “content” folder, but just in the root.

Why do developers insist on hardcoding these paths while these are all options that can be set in the wp-config file.
