In over 4 years on Subeta I've actually never accidentally donated anything.. So its just a matter of being careful with your items.
Sorry to hear that. I've never lost anything in that way, but I really get scared when I stock my shop. I always pay extra attention to my lizard trap and spray. Well, it would probably be helpful to have a pop-up window.

Never had that problem. Sucks for you though, sorry.
^this.
I don't want to quickstock system to change, because people are going too fast. May it be with popups, spare columns or whatever, it works fine for me, and has worked for me for two years.
Changing the system with new columns might even end up in MORE accidental donations, due to the fact we're used to the old system.
I voted, but I also agree that people should check first. Though I do understand the problem also.. Maybe try sending the items you're keeping to your Vault next time. Then you can just quick stock the whole inventory, and solve the worrying issue. ^_^
I agree with Tche, making the donate section different some how might make even more mistakes. One thing that it different from the rest tends to draw your attention to it, and you might click it. XD
I think there should just be an option for Lizard Traps and Discount Cards to 'permanently' attach them to your account. no popup bullshit, or mistakes.
If not the above, more space between the collumns alows you to easier 'see' what item belongs to what collumn.
You can triple check, but sometimes things just don't pop up in ur eyesight
Aww, I'm sorry :/. I haven't done that, but that's because if I decide to mass stock or deposit things, I put the items I would like to keep in a trade or in my vault.
Edit: Stijn, that's a really good idea about 'permanently' keeping items in your inventory.
