I think you should be able to pause builders
Pausing builders would be a good idea if you have 0 builders left to build anything yet you have gold left that people can take therefore starting to build the new defence or whatever you are upgrading stops your gold from being taken whilst waiting for another builder to become free.
should've looked before posting
I guess someone already had this bright idea.
I posted my idea of how this should happen here:

I think it's a great idea for a whole slew of use cases, including:
1. last minute pre-clan-war prep
2. use up resources before a shield ends (ie, walls)
3. I think because of #2 there should be a penalty .... otherwise you could pause a builder 10 times to "start" 10 different buildings before taking a long break from CoC ... which wouldn't be fair to people raiding your base
thougths?
