Hi,

I know you're working very hard and I'm very grateful for this project, but could you write some (short) explanation why these changes where made? If I find strange behaviour I walk trough the history of commits and see if I can find anything why something is happening.

thanks again and cheers! 👍

Because plugin methods are executed in a background thread, but webview.load is required to be executed in the main thread and Xcode shows a runtime warning when doing it in a background thread.

Thank you!! If it's possible to give every commit some context would be super!
