# ztxt code editor

Over a year ago I created a code editor called ztxt for use in my classes. After a semester of use, I decided to start using ztxt as my main editor. It’s still in beta, but it works really nicely. Here is a short video showing how to get started with it:

To showcase ztxt a little more, I recorded this video showing how to make a localStorage based note program:

# New Projects

I have a few new personal projects up and running on github. Have a look:

https://github.com/ZevanRosser

Zapp
Simplified object creation, custom events and deep linking/routing

jquery.select-all
a different kind of javascript templating

OnionSkin
Canvas based animation tool inspired by Flash’s onion skinning

I may create a short video soon that walks through each of these projects.
