After an idea has shipped, we want to lock the idea from additional votes and/or comments.
This would be really helpful for us. We often have people add new ideas or issues to shipped ideas even though our policy is that no new issues or ideas should ever be added to shipped ideas.
Definitely need this. Can have an idea with a large number of votes > 500 and someone comments and 500 customers then receive an email about it, then they complain about being spammed. Need to be able to lock it so this doesn't happen.
You won't be notified about changes to this idea.
