+[EmailIt](https://github.com/raguay/EmailIt/) is a Wails 2 program that is a markdown based email sender only with nine notepads, scripts to manipulate the text, and templates. It also has a builtin [Node-Red](https://nodered.org/) server, scripts terminal, and the [ScriptBar](https://github.com/raguay/ScriptBarApp) program for displaying results from Node-Red or a script on your system. Documentation is very scarce, but the programs works. It’s built using Wails2 and Svelte, and the download is a universal macOS application.

+
+[Modal File Manager](https://github.com/raguay/ModalFileManager) is a dual pane file manager using web technologies. My original design was based on NW.js and can be found [here](https://github.com/raguay/ModalFileManager-NWjs). This version uses the same Svelte based frontend code (but it has be greatly modified since the departure from NW.js), but the backend is a [Wails 2](https://wails.io/) implementation. By using this implementation, I no longer use command line `rm`, `cp`, etc. commands. It is fully coded using Go and runs much faster than the previous versions. 
+
+This file manager is designed around the same principle as Vim: a state controlled keyboard actions. The number of states isn't fixed, but very programmable. Therefore, an infinite number of keyboard configurations can be created and used. This is the main difference from other file managers.
