We've created a text ticker widget which can read content from a remote text file and show it as ticker crawl.
Please find the widget in attachment and follow the steps to get it to work.
Using Manager Express
Simply drag and drop the widget into the playlist and add a "url" option with value as your text file URL
Using software which doesn't allow parameters for widgets
You will need to hard-coded your text URL into index.html for it to work:
1. Rename widget to zip file
2. Extract zip file and edit index.html
3. Edit line 29 to point to your text file on web (can be files on Dropbox and other locations which is served from a HTTP server)
4. Zip all files into a zip file (remember to keep index.html on root folder of your zip file) and rename it back to widget extension (e.g. wgt)
