Option to configure portal so that when user "x" log in, he must see his own gallery on home page and when user "y" log in, he must see his own gallery and also these users should have the capability of changing banners.
This is a great idea hope Esri takes it up. In addition to improving the user experience this is really needed from a security standpoint.
There is a commercial package available for doing this. I've worked with it a bit on AGOL, where it's free.
Otherwise it's $500/yr/portal which seems quite fair.
I haven't really used it enough to have a valid opinion. But of course I have one anyway: My impression was that I'll wait until our Portal usage is high enough and users are complaining about these issues.
Then I'll take the time to build it up and administer it. My recollection is that it takes a bit of work to setup and to continue to keep it polished.
But it looked like it would provide that basics that most folks seem to want for separating out home views.
