Commodore 128 has 2 video subsystems and this allows to use 2 desktops. For VDC desktop is designed IDEA UI and for VIC-IIe desktop is designed cLIVE UI. Both can work together or in single desktop mode with user selection of active UI. When is active IDEA UI, computer can run faster, when cLIVE, computer can use Video RAM as RAMdisk.

calculates as so low as possible lowest requirements for use on each machine. I was inspired by Windows 8 UI, maybe it's for anybody plagiarism, but with lowest capabilities everybody must to calculate what to do with 40×25 text screen or 320×200 pixels in 16 colors resolution. I found this solution and my inspiration is my decision only. Everybody knows that Windows 8 was Microsoft's first attempt to touch based interface and I plan support of lightpen or other touch device.
At start of system cLIVE displays start screen. On start screen are displayed pre-selected apps (possible to change them) and bookmarks bar of main groups. Quasi-Live tiles displaying files opened in apps.

320×200 pixels 8×8 color cells 16 colors and sprites
320×400 pixels 8×8 color cells 16 colors interlaced and sprites
37×50 textmode interlaced
