Path to materials.lib

Hello,
maybe i am wrong, but i have to copy materials.lib every time i install a new version of PrePoMax.
A link does not work. This is a bit anoying. Could a configurable path (in settings) to material.lib be a benefit?

Currently, you can add material libraries this way:

But such a setting for the default library location could indeed make sense.

Thank you for the hint. I never expanded the menu under Libraries!
