What would you like to happen for vacation mode?
Are you saying you want to disable the store? That’s bad for your business - it will damage your SEO and your brand reputation. (if someone comes to a broken site they probably won’t come back… and search crawlers will take notice).
Are you saying you want to stop taking orders? Why not just fulfill the orders when you get back from vacation?
Are you a small team that fulfills in-house? All good, people love small teams, just add some text in your order confirmation email that "we’re a small team and give each order personal attention, we usually ship orders within 3 business days (or whatever you want to say).
Instead of getting angry, identify the exact problem you want to solve, then brainstorm solutions (or ask us here in the forums ?).
