In regards to the CW shop search in the Beta wardrobe, you can't seem to switch between it and the All Items CW Only. If you're in one, it won't change to the other. It's especially confusing if trying to look through CWs for sale and see them both, for sale and not, combined.
When you're in the CW shop section, there's no way of getting back to your own items.
Also, GAs are allowed up to 3 items per layer. I put two on my head layer and got an error saying that I had too many and I need to buy more. I tried putting 3 on my hat layer and no issues. I get this with different layers from time to time. Maybe this could get looked into please?
The Error Message
You can only wear 3 items on your head layer! You are currently wearing 4. You can purchase an additional slot for 75,000sP for 1 month!
I got this when putting an HA together with only 2 head layers. I believe that the hair salon layer is its own layer. I don't want to pay for something that isn't needed to be paid for! I can't wear what I want cuz of this.
Head layer isn't the only layer posing this problem, either.
Finally, searching for items. I tried looking tiara up, for example, knowing that there are a number of them. Two came up. I think there's something wrong with search.

Did you try saving despite the error message being there? I've found that when I load a shared HA to modify and save, it counts my layers wrong as I'm putting them on, but it still saves the HA correctly.
