Thanks for fixing the issues. Approved but please fix this warnings in the next version: Some code called array.toString() on a Uint8Array instance. Previously this would have interpreted the bytes of the array as a string, but that is nonstandard. In the future this will return the bytes as comma-separated digits. For the time being, the old behavior has been preserved, but please fix your code anyway to explicitly call ByteArray.toString(array). (Note that array.toString() may have been called implicitly.) 0 toString() ["self-hosted":544:0] 1 parseStat() ["/home/ice/.local/share/gnome-shell/extensions/simplenetspeed@biji.extension/extension.js":82:19] 2 enable/timeout<() ["/home/ice/.local/share/gnome-shell/extensions/simplenetspeed@biji.extension/extension.js":228:15] To fix that you need to do this: const ByteArray = imports.byteArray; let prepare = (out instanceof Uint8Array) ? ByteArray.toString(out) : output.toString(); btw, you can also move `settings = Convenience.getSettings(PREFS_SCHEMA);` to enable() if you like. Also it is needed to use `button.destroy();` on disable() after removing it from the panel. If you you need help please ask us on GNOME Matrix channel: https://matrix.to/#/#extensions:gnome.org
