-- **An idle window stays idle when the file tree is watching a busy tree** —
-  the file tree watches its root recursively, so it hears about every write
-  underneath: `.git` internals, build output, everything under `node_modules`.
-  Each of those batches repainted the whole window, several times a second,
-  including the overwhelming majority naming a directory the tree has never
-  listed and does not display. A window with nothing new to draw never reached
-  render idle, which is what issue #243 reports in its title. A batch now
-  repaints only when it reaches a listing the tree actually holds *and* the

-  rather than by asking for a paint in order to get one. `.gitignore` edits keep
-  their whole-cache refresh, but only when the file governs a directory the tree
-  is showing or loading: the one an `npm install` unpacks into each package
-  under `node_modules` reaches nothing on screen and now costs nothing.
