Seems good

[prusnak]

When I set EUR in the dialog once and then go to pay for another request, the unit is set to EUR again. Maybe we should reset it to sat every time the dialog is open?

But if you say that it is preferred that way, to keep the preference persistent, I am OK with that as well.

Otherwise the frontend changes look nice!

Resolved conflicts, rebased on top of the current dev.

@dni What is your take on this? If you want to keep it persistent, I will approve and merge.

hey @prusnak! i look it at again and after i tried it i thought that when i selected it once, i probably want to keep going in that currency and not have to select it again at least for the current pageload. i dont think not reseting to sat is a problem.
