The disappointment was, there are no differences.... I am talking about the hardly readable text on the buttons:
- preview and customize
- done editing
So I wanted to create a case on BtBb.... but you can only make cases for installations connected to your own institution...
The added printscreen is made at: https://preview-learn.blackboard.com/ultra/tools/portfolios
So, knowing Blackboard cares about accesibility, I expect them to solve this minor issue.
Don't know how many institutions within the US use the Bb-portfolio, within the Netherlands a few, within Europe probably a few more
So I just wanted to share my experience here.
