I would really like some kind of reticle indicator for which weapon action bar I am using. I use 1h/shield for both weapons so it can be difficult to tell which bar I am currently on. I think an add on that would simply rotate the reticle 45 degrees when on weapon 2 would be a nice heads up indicator for which weapon bar you are on.
This add on looks like it is trying to do a similar thing but if instead of the icon there was an add on that just rotated the reticle 45 degrees for the second weapon it would be a lot less intrusive.
