@Jack Rusher Thanks a lot for bumping that Philippa talk. It was well worth the rewatch. Summarizing, it sounds like the key ideas for scalable, discoverable UIs are: • one-level menus • off to an edge so they don't obscure people's stuff • that are context sensitive • that show keyboard shortcuts • that expand to something like a ribbon bar when you click on them • that allow searching to filter through their contents This makes a lot of sense. I'll move the palette to the bottom and blend it with the wordstar-like menu I've done before. It's already context-sensitive, though in an ugly, hard-coded way because it's quite a simple tool at the moment and there's only a few context-sensitive exceptions. --- I'm still thinking about focus follows mouse. It's something I've never used before. But I think I see where you're coming from; the current metaphor is already focus follows mouse to some extent since stuff outside the viewport implicitly goes out of focus. Why require an extra click to switch panes within the viewport. Would you prefer focus follows mouse with all panes being editable? Or should I perhaps restrict focus follows mouse to only when a pane is not being edited?
