I have gone through 3 or 4 classes since I started with Mobile: Ed courseware. my current class is a start of a series: CO101. This is the First class that I am seeing these "mark ups"/visual references for start and stop locations for suggested and extra reading links. many times the reading is vague as far as where to stop especially (though where to start is problematic if the link isn't working correctly, as I have noted in a bug in another thread elsewhere).
So, just wanted to say thanks for these visual references, great Idea. I hope they are implemented in all the courses even retroactively. wow.just.wow, this simple little thing us tremendous addition for those of us that actually read through all the reading as available.
