I'm quite sure it would be easy to list "my sites" (current user site memberships) in a design fragment.
Massive web research wasn't successful.
Currently I'm using
[@liferay.user_personal_bar/]
which contains "My sites", which cannot be displayed expanded.
Which macro does the trick? Im thinking about something like
[#assign mysites = someUtil.someMethod()]
which I'd use in a custom pulldown instead of the personal bar (and - if possible - just add a logout to the my sites list).
