While they've not said much about your other requests, I know that they've said that with Book 10 one of the things coming is scaling of other ui components.
They've not said much more than that, as far as I know...it's all fairly hush-hush, and I can understand why. I'd hate to see this place, and the LotRO forums, if they say they're going to release something specific and it doesn't work out. lol
