Provides options for changing text size and colour scheme. Settings can be saved to persist between sessions. Also integrates ATbar from Southampton University ECS.
Moodle 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9

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.

Please dont report bugs here

If you experience an error with the block, or would like to request a feature, please use the "Bug Tracker" link below.

    Hi Mark, Great block...and here is some 'Good news', just to say this block works OK in Moodle 2.6 Alpha. At least in the pages I have tested so far. Admin and Frontpage. I will keep testing and if I hit a pot-hole will let you know! smile

    Hi Chris,
    It seems the text size CSS is too hacky (or not hacky enough) for some themes. There's a possible solution on the project's issue tracker which I'll try and review this week to see if it solves the problem.

    Hi Mark,
    Is this block compatible with the Clean Theme i.e Twitter Bootstrap version ? From what I see , it only affects the Header and the footer for now ( clicking on A+ for eg., expands only these 2 regions ) .

    Hi, having a few issues with the plugin. Whenever I change the theme and then try and 'reset' the webpage to revert the changes. Nothing happens. I've tested with multiple different theme options. Only way to fix it is to uninstall so it deletes the database entries.

    I've tried the comment method in database.php. Still doesn't work.

    Any suggestions? Thanks

    Hi Bradly,
    A new developer is currently working on many fixes to this block. If you download the latest version from GitHub[1] you may find that your issue is fixed. If not, please report the bug there, and hopefully Hrvoje will be able to assist.

    Many Thanks

    I have a local installation of Moodle 2.8 and the plugin does not work. Is it my fault or you need to upgrade the plugin?

    Dear Matthew and Alex, the new version of a plugin published today 2.2.2 works with 2.8 now. Have fun!

    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,theoretically it should work with 2.9 .however it would be a great help to the community if you could try and let us know if there are any issues with it.

    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.
