I just installed the plugin font size in Moodle 2.7+ (Build: 20140703). In the text editor I can't see any change in the code when I toggle to plain text in Google Chrome. Same result in Mozilla Firefox. There is a change of the font size, but it doesn't "stick" or it's not applied properly, meaning I can see the change in the text editor before I toggle to plain text or save the text.
We update moodle every week and most of the plugins are detected and updated but Marking Manager is not, it says Missing from Disk and then you have to find it.
Please, can you make it so that it automatically updated when you update moodle as we use a lot of your products?
