It's not really an issue.. more of a suggestion. But if for example you look at the Foreman UI, everything is categorized and if for example you want to modify X it's right there under the obvious menu option. 

When it comes to oVirt, the documentation isn't as readily available and for example if you wanted to modify the network configuration it takes about 10 different mouse clicks to get to where you want, and then sometimes it errors and then you need to refresh the page or something. The general feel, maybe it's just my setups but the login process always takes between 30-90 seconds, probably to load all the javascript etc. A simple HTML + jquery approach similar to Openstack / Foreman would be much cleaner experience. 

Whenever I've showed oVirt to other people. They've always mentioned how slow the UI experience is, different from the stereotype of being able to do things more effectively on Linux compared to Windows.

Obviously I'm looking from just the Administration portal POV, and my suggestion isn't really critical as it doesn't effect what matters most (VMs, Features etc.) but it would really bring oVirt to a new level visually and make it a little more appealing.

Apologizes for the poorly formatted ramble.
