Hello Themers,
I have been working on a new solution to implement left to right / right to left language swapping capability in themes (see: https://moodle.org/mod/forum/discuss.php?d=264955) and after discussions with David, this is planned for the next release (2.7.8). However, it is radical. Therefore if you have a test server and can do so, then please can you test.
You can get the code from: https://github.com/DBezemer/moodle-theme_essential/archive/master_249.zip - please do not fork this branch though, as I push fixes to it and rebase it against the current development. Its separate as it falls in line with the concept of a 'feature branch' to make it easier to maintain the development of it at the same time as the main push.
I would be grateful if you could either post screen shots here or on the issue: https://github.com/DBezemer/moodle-theme_essential/issues/249 - you do not have to even be using an RTL language as some aspects of LTR may have been altered due to the ordering of CSS file imports.
I cannot stress enough that this MUST not be placed on a DEVELOPMENT server.
Essential development relies on the support of the user. You have the power to help us improve and make the theme better for all. Please help.
Thank you,
Gareth
