04Questions

What does it contribute?
Four things: a Finder context action ("Open as table") on .csv files, a file handler that opens the same table panel, a preview renderer so Finder's Preview pane shows the parsed table instead of raw text, and the panel itself (panels/table.html, a sandboxed webview).
What permission does it ask for?
fs:read:home, so its worker code can read the .csv file the panel is opened for. It writes nothing and reaches no network.
