Wow, good to know! I'll try it next time!
Literal
Good thing [object-を] heard! Next-time try-[let's-ようっと]!
~ようっと is a casual, musing volitional — often written with the っと ending for an 'I'm gonna ~' self-directed tone. Set against the plain volitional ~よう, the っと adds a lively, self-promising feel. Natural youth/casual register.
