I don't know, but I suspect that doesn't change anything because KDirWatch
will simply add inotify-watches for all of the subdirs.

Right.

Ah, right. Didn't think this to the end. You can add an action to
projectmanagerviewplugin.cpp in contextMenuExtension. If you want reload to
work on a fine-grained level we need to API for that - probably on
IProjectFileManager. When that is in place we can have a refresh action in
the context menu which fetches the manager plugin for the project and calls
the reload() function.
