Overhaul the UI to use webviews #2
Description
The RN UI is currently build all in RN. This makes it very time-consuming.
We're for the most part unable to re-use the web-UI because it depends on loads of dependencies that are not suitable for RN. There's also the polyfill issue that's not easy to resolve.
If we want to make this easier we should consider this:
Using web-views with the manager's UI in it for rendering the explorer & addons.
