Expressions should be persistent.

[Sylve]

Yes I would like this option. I like standing with my globe drawn in the alternate pose because it makes me look more friendly.
<---- How expressionless I seem.

My idle face looks quite grumpy all the time, but she has a small smirk when she stands there with her gun drawn ... I find that amusing.

Edit: On topic ...
I'd like to see them add in a kind of 'changepose' but for expressions.
Set it up like the /random idle pose option in the settings, or even allow us to select from a pool of expressions to randomize.
