[Eco Bounty] Purchase & UI Issues on Mimo NFT Marketplace

Target: https://nft.mimo.exchange/
Severity: High (Affects Purchase Flow and UI Accessibility)
Category: Transaction Logic / UI/UX

1️⃣ Issue: Unable to Purchase Single NFT When Multiple NFTs Are in Cart

Summary:
When multiple NFTs are added to the cart, users cannot purchase just one item. The marketplace forces a bulk purchase or requires manually removing the others before proceeding.

Steps to Reproduce:

1. Visit https://nft.mimo.exchange/.

2. Add two or more NFTs to your cart.

3. Try to buy just one NFT (without clearing or removing the others).

4. Click “Buy Now.”

Observed Result:

• All NFTs in the cart are selected for purchase automatically.

• There’s no way to choose a single NFT to buy individually.

Expected Result:

• Users should be able to select one NFT to purchase from the cart.

• Other NFTs should remain stored in the cart for later checkout.

Impact:

• Restricts user control during purchase flow.

• Causes confusion and potential transaction abandonment.

Recommendation:

• Add a “Buy Selected” or checkbox selection option for each NFT in the cart.

• Preserve cart items after partial checkout.

2️⃣ Issue: Feedback Button Cannot Be Removed or Hidden

Summary:
The Feedback button on the bottom right of the marketplace UI obstructs part of the page and cannot be closed or moved.

Steps to Reproduce:

1. Go to https://nft.mimo.exchange/.

2. Observe the floating Feedback button in the bottom-right corner.

3. Try to close or hide it.

Observed Result:

• Button is fixed and non-dismissible.

• Obstructs other clickable elements in the lower corner (e.g., purchase confirmation, balance info).

Expected Result:

• The Feedback button should be minimizable or closable.

• Optionally appear as a floating icon instead of a large overlay.

Impact:

• Affects usability on smaller screens and overlaps important UI elements.

Recommendation:

• Implement a dismiss or minimize option for the Feedback button.

• Ensure it doesn’t overlap functional elements.

Overall Impact

Both issues affect the user purchase experience and UI accessibility of Mimo NFT Marketplace. Fixing these will improve transaction flexibility and platform usability.
