wtaskman is a Rust / webkit based task manager, similar to the Windows Task Manager
Not yet finished, only in the prototype stage.
A notable feature is that it uses the native Web-rendering engine, i.e. MSIE-Renderer on Windows, webkit2gtk on Linux, Safari / Blink on Mac.
Currently it only works on Linux, where you will need to install: webkit2gtk
sudo apt install libwebkit2gtk-4.0-dev
