Moodle Is Great! It's Open Source! If you need more functionality, just add a plugin.
WAIT. HIT THE BRAKES RIGHT THERE.
Yes. It's open source. But that isn't helping anything. When you find a plugin that does The Thing You Need, you find that it's for a version of Moodle that's several years old and was written by one guy who hasn't touched it since 2014.
There are some plugins that are great and up to date. They are not Open Source. They cost real dollars and aren't terrible.
But if you want Moodle because it's FOSS, then your motivation is wrong.
The one largest problem with Moodle is its dependency on plugins and the consequent decentralization of core functionality. The core UX itself is shit because it needs to open space for plugins to change it and because it was created as a set of independent plugins itself.
But yeah, if you need more functionality, just write a plugin.
