The block allows users to customise Moodle to their visual needs.  It supports changing of text sizes and colour schemes.  Customisations save to the user's session, allowing them to persist between pages, and can also be saved to the database allowing them to apply permanently.

The block also integrates ATBar from Southampton University ECS. This provides extra tools and customisation options, including dictionary lookup and Text-to-speech.  Visual customisations performed with ATBar don't currently persist, and can be used as well as or instead of the block's own customisations.

    This is a great plug in. We installed this in Moodle 2.7 and works well however, the ATbar doesn't work for students when in an activity. We ticked "always" when launching but only works in teacher role or higher. I've tried to tweak settings but can't seem to find the root of the problem. Would be great to have a solution as the text to speech is fantastic for learners with difficulties in reading. I welcome your advice smile

    this is a very nice block! It works very well besides the fact that you have to add the block to every page.
    To avoid this, I've made a version of the clean them in high contrast mode (it has a custom frontpage, but you can remove it ;)
    It is on github:

    Kind regards,

    Hi, has anyone had success in using this plugin for V3.0 or v3.1 and is there an intention to officially release an update before Sept 2016 to work with 3x? Many thanks.

    Hi, I am using this plugin for Moodle 2.9. I was wondering if we could change the A contrast icon as a text 'Contrast 1' etc. because our user might not know what A means?

    Sarah, Hittesh and I have are discussing plans for the next release of the plugin. I would hope that we can have an updated version out before September, although I can't commit to any particular date as this is currently a "spare time" endeavor for me.

    Hovering over the icon should display a description of what each button does. There's currently no mechanism for changing the displayed text per-button (only chaning the A to a different character/string throughout by overriding the language string).

    Sarah and Mark, I have just installed this in Moodle 3.0 without any problems, at all. I've done some quick testing and it seems to work just fine. Note that I don't use this plugin, myself, so I my testing is pretty superficial. However, I clicked on every button and got the expected results.

    Hi Mark,
    Thanks for your reply. I am working with St Nicholas Home from the blind and the users have a problem with the A on their screen since they are using their keyboards and open source the screen reader called NVDA. So, my colleagues are trying to explore if we could change any label on the code for the block.
