I know this has been addressed in previous feedbacks with NO descernible attention paid by devs, however when trying to find this morning, it was not found under search terms that I believe it should have been found by. I know at least one of those feedbacks included a response by me, which I have NOT been able to find in many months.
So I am adding this correctly in anticipation of someone finding the correct feedbacks AND LISTING them so I can bump them, or someone writing a better feedback to address this issue.

I consider clients improvements of this nature of extreme importance to the continuing health of Foldit, and I am far less then enthusiastic that I and others have to keep our clients open all the time to stay in touch with them.
