Every time I create a new lesson for the Portuguese library and import it, I have to spend a lot of time deleting tags that just don't fit that particular lesson. I guess the system gets all the tags that were used in all the course, but this is not practical. I'd prefer the tags field to be blank, and then I'd quickly add 2 or 3 tags. Another option would be the possibility to select just those that I want, by checking from a list, or to deselect them all.
You have recently changed the format (from square to oval) and size ( from 120x120 to 200x200 pixels) of the images in the courses and lessons, and now all my images in lessons I created some time ago lost quality, are pixelated or cut where they are not supposed to be - is there anything I can do besides uploading dozens of new images?
