I don't know when this feature went live but I am in love. When I clicked on a plushie in my inventory, under Other Options it says "Already in your plushie collection" and no longer has the 'add to plushie collection' feature.
This will save SO much time clicking to add something just to get that error saying I already have it, then have to go back and add it to my shop. Thank you!
[Edit] Looks like this applies to beanbags as well. AND ALSO TO FOOD! If you go to feed your pets, it lets you feed any of them, but gives a message "(They've eaten it before!)" next to any pets who have already eaten that item!
This is some seriously fine thing!
I LOVE THIS. God knows I don't remember which of a thousand plushies I don't own. I hate the extra few seconds that the error message took-- it seems little but it was honestly so aggravating. So thank you. <3
Saves an extra click here and there. And ill take it.
Oh yeah, doing the happy dance! Definitely a wonderful feature.

Yes, thank you for this! I was so happy when I saw it!
(is this newer than the food thing, or were they implemented together? I only just noticed it now, but then again most plushies go directly into my shop via quick stock ^^)
This is a really great change! Now all I need is for this to extend to the wardrobe, too.

Oh this has saved me so much time lately ! Now if they could implement this for the wardrobe...... please please please.
collecting I love this feature, it makes thing so much easier, even if it is just a few less clicks. Also seconding in hoping they make one for clothes as well!
These are possibly the greatest features they've ever added to the site. The time saved by knowing whether I need to add or have already added a food, wearable, plushie, or beanbag is immeasurable.

This.Is.Awesome!
This is one of the best features Subeta has added.
I was crazy happy when I noticed that too. My mind just went "Finally!" FYI trading cards too. I'm willing to bet it goes with any collection, like pumpkins too.
oh thank goodness. this is so many years overdue lmao i guess i have no excuse now, i need to start collecting again.. :(

I was so happy to see that! Also, if you go into your collection, there's an option to add all the beanbags or plushies that are in your inventory, to your collection. And it will show you the ones you're missing! I'm not sure how new that was, but I just figured it out. Back to collecting again! :)
I like it!!I absolutely HATE those error messages, and I even hide the screen with my hand when I think I'm going to get them if I think I already had it, but now that it tells you before you can put it in there, I don't have to worry about that anymore!!
