I have 3 Ideas

1) if you are creating a wormhole to a stargate from your own/tribe the remote shield should deactivate automatically, so you don't have to worry about it.
1.1) add an extra button into the remote device to "deactivate" it
1.2) for local gates an extra object to activate/deactivate the shield would be nice (so you don't have the long wait time to activate/deactivate the shield like on the dhd)
2) activate the shield/deactivate the wormhole after X seconds after you moved through it. This should be an optional setting through the dialing sequence.
If you travel across the island the client sometimes takes a while to load the new location. in the meantime other dinos, enemies, ... could go through the gate and kill/damage you/your base. so it would be good to have a little security here

3) I want to hide specific stargates from the dial menu&history so that you can only visit it if you know the sequence(similar like the lost temple).
