Thanks for this Dipsy. It's a great looking interface.
Perhaps there should be a notification when submitting an order on the mobile order entry. I found myself clicking submit a few times just to make sure the entry went through.
I like and dislike how when you move a unit it only shows the territory you can legally move to. Example: Moscow can only move to 5 adjacent territories and those are the only ones listed. This does two things; 1. Helps users quickly select where they want to go as there isn't a long list of territories to choose from and 2. This will prevent people from entering in illegal moves.
Preventing users from entering illegal moves is something that's been discussed before. It can change a few things. Especially in Gunboat when you're trying to signal to another country or you purposely want to 'mess up'. The flip side is having a huge list of every territory int he game when you're on mobile just trying to enter in quick orders.
This also creates another problem with support orders. I'm using DummyB playing as Germany. My Ber (Army) can't support anyone but their own territories. So I can't support Paris into Burgundy or anything like that. I can't even use Munich to support Kiel into Moscow. (Not that I'd want to but I should be able to)
I am also curious as to will this mobile function be forced upon mobile users or is it an option. I really like the interface and think it works great however I truly dislike it popping up a second tab. Personally, I like to see the map while I’m putting my orders in so I can double, triple check everything. Also, with more than just three or four units. I can see myself going back and forth quite often from the Map Tab into Mobile Entry order tab, then back to map to see my outstanding units that need orders then back to order entry etc just to get ten or so units all done.
The order Solver on the main site allows you to pull a full list of each unit that the country has and is in need of orders. Like this;

Is it possible the mobile entry order function can do something similar? Instead of giving us one territory to select from, it could list all the ones for our country and allow us to input orders then submit from there? I think this would help when people have more than just a few orders to enter.
