I am shortly going to reorganize the Trimmed Reqs on profiles/UCP in an effort to shorten the list substantially (grouping similar tasks). During this time you will not be able to edit your profile requirements.
Moving requirements around isn't supported, so almost all trimmed req data will be lost.
I have finished reoganizing the Trimmed Reqs, and you can now edit your profile again.
I've tried to group similar tasks into related groups to try to save a lot of space on the Profile. If you feel anything has been miscategorized, or is missing, or if you would prefer something taken out of a category, let me know in the comments below.
