I would like to see the Support Portal not auto-refresh auto-log-me-out while I'm working in there.
I too often get booted out of drafts of support tickets by being auto-ejected and logged out of the support portal and community site. I'm just actively typing along in the Case Comments box, and the page refreshes and I'm logged out, losing all my work in the process. Of course, this is my reminder to stop using the Support Portal UI for drafting my comments, but it's so tempting to just work the way I expect to be able to work, and then I forget and get burned.
