I need to use a Windows machine at work, but I also bring my own MacBook Air to supplement my computery needs…

Space 1: NotePlan (think FoldingText but include a calendar/daily notes) and NVALT
Space 2: Assortment of Safari windows (I do the Siracusa-method of grouping tabs by related topics) and Spark
Space 3: Ulysses
Space 4: Fantastical
