Resize dots on the bottom right have been removed, obscuring the ability to resize the window.Convention-defying checkbox categories (System, Windows Explorer, etc.) obscure the ability to click the category icon to select all items within that category (ditto for results window).Grey buttons on the right side in certain options menus, along with dull grey obscure text, makes them seem unusable/unselectable.Fuzzy light grey text for checkbox items makes it seem like they're greyed out (unselectable).Lack of scroll bar center notches (or similar long established conventions) makes it ambiguous which portion of the bar represents the current scroll position.'Windows/Applications' tabs make the selected tab smaller than the unselected tab.dropdown boxes, checkboxes, etc.) inconsistently sometimes respond to mouseover and sometimes don't Items in the main Options window (e.g.UI does not meet user expectations based on 1-2 decades of standard convention in so many ways:.Registry button used to use the Windows registry icon (a 4-sided 3x3 Rubik's cube, sort of) but now uses a generic four square icon which was completely made up and corresponds to nothing whatsoever, and the icon next to the 'Registry Cleaner' header uses NINE cubes rather than the four in the left-hand icon!.Title is centered rather than on the left, next to the program icon.Solid colour buttons and solid colour background in general just look simplistic and lazy and 1990s.

No options to customize the UI in the settings.

Bottom grey bar is different grey than the left vertical bar's grey, in addition to being wasted space.

White title bar is just butt ugly and completely out of place with the greyness of the rest of the UI.

I created this account just now for one reason and one reason only - to echo this sentiment that this UI has got to be one of the most disgusting UIs I've ever seen.
