Returning some functionality removed from KDE

Hi! Is it possible to return some behavior of KDE 3.1 and KDE 2? My impression that some things became much worser with later versions of KDE. Namely, - They removed the 3D appearance of Kicker. First from KDE 3.2 they removed the frame around the taskbar buttons and make the buttons larger (I would say, too large). Next, from some later release they removed 3D appearance from taskbar buttons, so they are not pushed like other buttons any more, only the bold font shows which application is currently selected. - Is it possible to make an option to remove the thick separators from the K menu, like it was in KDE 3.1? - In KDE2 when you press K button and then launch another application, the menu does not disappear, this makes easy making screenshots - In KDE2 when you hover over the quick launch items, the icons are enlarged. - In KDE2 when you press "minimize all windows" button and then klick on a folder on desktop, only that folder opens in a window. In KDE 3.5 all windows restored. - In KDE2 the frames around names of items on the desktop are dotted like in Windows and shown reliably: do not twinkle when you press mouse on another place on the desktop and always shown completely. In KDE3 they twinkle and sometimes shown only by half. The names of items in KDE2 shown exactly in the center relative to icon while in KDE 3.5 the names often shifted from the middle. - The K menu in KDE 3.5.10 is often shifted when displayed first time after reboot or changing settings. This depends on the icon theme used: all OK with Crystalsvg but problems with Slick, KDE Classic and others - I would also want see more exciting icon themes and Qt styles which one can see on the old 200-2005 screenshots.
