Most of the things I make in Vuo are little helper apps for other software to use. e.g bridges between DAW record state and IFTTT home automation. Face tracking to send OSC to video servers.OSC translators to sync lighting boards and audio playback software etc.
Every app I've made, the first request from the user is always, "Can you make it so it opens in the same place as when I closed it like every other Mac app." It's a real pain having to add all the nodes necessary to achieve this and it is really spoiling my enjoyment of the product.
