Problem: owner might not want a particular user to transfer NFT to another user

Problem

The idea is cool, but sometimes (most of the time?) the owner doesn't want the user to re-assign his permit to someone else.

Proposed solution

When NFT is minted, let the owner (minter) specify if he wants this NFT to be transferable or not.

Hi, thank you!
Yes, thank you for problem reporting and solution proposal.
I agree with you, some use scenarios must block transferring tokens, may be except "token burning" (transfer to 0x0).
I'll prepare commit for this feature.

Actually, maybe you should keep the transfer. But, make it approvable by the owner.
So NFT holder can initiate a transfer but must be approved by the owner.

That's right, transfer of tokens and NFTs should have the approval of the owner
