Hi Titus,
any suggestions on how to solve the problem with the MoveToElement method, please?

I think what needs to be decided here is how we are handling all of the HTML5 functionality across all the languages.

Next step is essentially an inventory of which of the storage/cache/location things are being supported by JS and which have been removed and decide which direction we want for all of the bindings.
