I am always keeping an eye out for useful MODx resources to share. I recently installed the EditArea Plugin on our Pleth site and at first glance have been happy with the results.
If you are not familiar with EditArea it is:
a free javascript editor for source code. It allows you to write well formatted source code with line number rotation, tab support, search & replace and live syntax highlighting.
Once installed it allows you to toggle EditArea with the normal text editor in MODx. When I am dealing with large pages of content I often find it is easier to copy the code into an external text editor (Notepad++), make my changes and then paste it back into the content area. It should definitely prove to be handy as a development tool since it’s additional features make working in your content code a little bit easier and faster (no external pasting). It is also worth noting that the creators of the plugin have put together a really simple installer:
The installer is a multilingual derivitive of the new MODx Evolution installer and drastically simplifies the Installation/Upgrade process.
