Finally, I turned back to the previous stable version. It works flawless to me, despite of its apparent age.
My suggestions, after trying the last beta for a couple of days, are:
1 - Rethink the way users approach utility programs lately. I believe people more and more look for COMPACT user interfaces and STANDALONE applications, even because the use of smaller screens/terminals is more and more widespread nowadays. Also, resources are never enough, expecially on net-laptops.
2 - The less invasive software looks, the more people appeal it. That means absolutely NO unwanted background services running, single-frame resizeable UI, NO to unuseful animations. Even today, a perfect exemple to me is the ancient Tweak UI. Plain and trustful style then, pithiness and no-frills is just what users need
