It should be noted that due to the fact that it is currently in a relatively early stage of development, there are many minor issues, but there should not be any issues that will significantly affect the user experience.

Everyone is welcome to use GitHub to report issues/provide suggestions!

    Maybe I am doing smth wrong, but using link above I get: 

    Minified React error #185; visit https://react.dev/errors/185 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

    And using local version:

    Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.

      Sorry, have been busy preparing for my final exams lately, and the notification icon is really too inconspicuous; I’ll look into the issue when I have time.
