Using iPad in Support Community - Issues

How can I stay logged in longer on iPad? If I leave the Page inactive and use other pages, I often find that I have to sign in again. See below.

How can I quickly get back to the community page I was on when I sign in? I get taken to the home, where (almost) all the communities are listed. See below.

How can I make sure that the list of communities is not truncated? The last one I can see on the Overview page is the section on desktops, which only lists iMac and Mac Mini. Seems that the Mac Pro is hidden, and maybe more stuff as well.
