Features

• Displays customizable fixation text.
• Supports background images based on position.
• Adjustable font size and duration.
• Collects trial duration data.

Additional Notes

A verification of the contribution's functionality may be accomplished by using the example file and the testing file.
A later PR will consist of the addition of a link to a website, created to help researchers use this plugin (and the two other VAAST plugins) to create VAAST experiments.
