[Users] so, what do you want next in oVirt?

[Andrew Lau]

A lot of work.. but has there been any consideration into redesigning the
web UI? Right now it's so complex and heavy, takes a while to load and too
many features are hidden! I've been using oVirt for half a year.. and I'm
still finding small useful things hidden here and there.

In comparison I like how Openstack has a lovely interface which hides its
thousands of complexities behind a clean interface.

Just a thought..
