iPhone 5S 64GB, iOS 8.3.

First, should any gamesas dev or rep read this: on the whole this game is very enjoyable, and thank you for not crippling it with micro-transactions.

Also, all comments relate only to the iPhone 5/5C/5S screen size, where relevant.

User Interface feedback:

When attempting to locate a Dweller from the Vault list, the zoom level is insufficient to allow the user to distinguish and then select the chosen Dweller, especially when there are many Dwellers on Coffee Break in the area. Additionally, manually zooming in an attempt to find the Dweller disengages the Dweller's green glow, increasing the difficulty.

User Interface feedback:

Please provide the option of sending a chosen Dweller to the Wasteland from the Dweller's info/stat window. Dragging the Dweller all the way to the Wasteland can be a fragile process when the Vault grows in size and population.

User Experience feedback:

Please give users the option of disabling automatic zoom to Living Quarters when Dwellers "get frisky". A notification is sufficient.

User Experience feedback/bug:

Please prevent the game from kicking users out of a Dweller's Outfit or Weapon Selection menu when something occurs elsewhere in the Vault, unless it is an Incident. As the Vault grows, it can become increasingly difficult to browse those menus without being kicked out.

User Experience feedback:

Please provide an Undo Last Dweller Swap option when a Dweller is sent to an already fully-staffed room, thereby replacing an already-existing Dweller. Owing to the size of the iPhone screen, it can become quite easy to accidentally drag a Dweller when only attempting to move the view of the Vault.

User Experience feedback:

I notice this was mentioned in an official review: the 5S gets almost unbearably laggy over 140 Dwellers. On occasion the lag can lead to a crash to Home screen. I realise the lag is a hardware spec issue, and otherwise the performance is excellent. Perhaps some animations can be killed on lower-spec devices when Dwellers go over a certain number?

Possible bug:

On several occasions I've dragged a Dweller to the Wasteland, assigned an Outfit, Weapon, Stimpacks and Radaways, and tapped "Explore", only to find that Dweller wandering the Vault on Coffee Break moments later. Normally I would put this down to not tapping the, "Explore" button correctly, but I've noticed that the Stimpacks and Radaways I assigned to that Dweller would be missing from my Inventory.

I guess that's all
