Confess I don't 'surf' aimlessly like I used to - more targeted and for a purpose.
"We see these tasteless icons more and more on the internet"
Could you provide some examples?
I did a little research on ISO standards related to mimetypes and icons. There are, of course, the mimetype definitions, but when it comes to icons ... no ISO standard set of icons. What I saw the most ... an icon but with the three letter extension in caps across/layered on top of the icon. So, as an example, a 'color' background with TXT for a .txt file.
Also noticed in that UX course a survey results PDF ... what one gets from a survey really dependent upon those to take the time to take it. Students? Students of different age levels ... that would have been nice, but, obviously, responses came from folks that used Moodle - as teacher, as admin (not so much), or as a manager.
Wonder how a 6th grader or an Elementary School Teacher would have responded.
The reason I got into this ... on a K12 Moodle site (prior to pendemic) that was loosing interest with Elementary/Intermediate teachers, saw an Elementary School Teacher trying out her new IPad and using Apple's Office Suite docs - which wasn't quite working as smoothly as she wanted. She didn't communicate with me directly, above was an observation on my part. So I embarked on setting up mimetypes with Apple Office Suite icons. Took about a day ... got it to work as expected but too late. Teacher already moved on ... never to return.
BTW, that site ... now it's only a few HS teachers using and primarily as a Quiz machine. ISD has Google Edu and many have moved to Google Classroom.
'Another one bites the dust!'
"there is little chance that they will modify them or take any comments whatsoever"
I would hope that's not the case ... maybe providing an option to use old behavior. When developers stop listening ... it won't be long before users leave - never to return!
