An option to put a customisable announcement banner on the top of our store page would be highly beneficial.  Rather than just toggling your page between taking orders and vacation mode, users can announce vacations ahead of time, special offers, product unavailability, and more.  Currently the only place to do this is on the sidebar, which isn’t immediately visible and gets easily cluttered.  A small banner with a character/line limit would suit these purposes better without needlessly cluttering pages.
