Yeah, in terms of the resource demands, the following caught my eye from the client web page: "The app is built with
React and runs on
Electron." Checking out Electron, it says that "
Electron uses Chromium and Node.js so you can build your app with HTML, CSS, and JavaScript."
Perhaps the reason that it is gobbling up 280MB of RAM is that it has a browser (Chromium) and and JavaScript based Webserver (Node.js) built into it. This looks like an efficient way to program in that Electron allows them to basically package up their existing web-based SimpleNote client.
I'm glad to hear that Yuuki has stepped up as maintainer of this lightweight client (NvPy). Also glad to see Automattic writing a prettier client for those who like that.
