Let me help you WORKER

Dear Supercell and CoC community,
Greetings to you all and thank you for the pleasant time you provide through my gaming. My idea for the next patch(I hope I'm the first to suggest this) is about helping a busy worker. What I mean exactly is for example my TH atm one of my 3 workers is upgrading the Mortar for 24h, the second is upgrading a mine for 36h and the last has nothing to do just because I am out of resources and I cannot fight to farm some. What do you think of giving the opportunity to workers help themselves e. g. the free one to help the 2nd finish the mine faster (How much faster depends on you). I am looking forward to your response for my suggestion.
Best wishes to the community,
MachineGunStef.

Idea is ruled out, and you are defiantly not the first to suggest this, please read sticky's before posting an idea.
