1. Wrong gsettings instance (line 171 extension.js). You should use `this._settings` instead. 2. What is the reason for checking (line 146 extension.js)? Makes any issues if you don't do that? I'm asking that because it is like checking if the extension is enabled or not which is not a good practice and that can be bad in racy situations.

Hi! Thank you for the review! To address the points: 1. You are right! This is my bad, I will correct that. Nice catch! 2. This is not checking if the extension is enabled, but rather if there is a CSS class applied to the Panel. There is a setting that you can toggle that makes it so that the effect is not applied when there is a maximized window. In case this function is called too many times, it can result in the class being applied twice. I don't know what the effects of that might be but this is a just-in-case thing. I have done some more refactoring work on this but it is in another PR (https://github.com/petar-v/gradienttopbar/pull/27). I will submit a fix for those issues. I will fix the this._settings thing and rename the variable to make its purpose clearer! Thanks again! :)
