+# Sidenotes
+- config is stored @ `~/zutui/config.json`
+- so are `grades_cache.json`
+- in plaintext.....
+
+##### As of right now I don't see any MUCH better way.
+
+##### I mean we could simply encrypt and decrypt it during runtime, but... does it really make it any more secure?
+
+##### And we can't really store it in any form of a _hash_ as we have to log in everytime with plain text anyways...
+
+##### However feel free to pull request if you're smarter :)
