KDE 4.1 Alpha 1 was just released, and it looks very promising indeed! Here’s what bastion of PolishLinux had to say:
First thing worth noticing is the new looks of KRunner. Unfortunately, on the current stage, it behaves in an unpredictable manner. In some cases after typing one letter I had to wait a few seconds for KRunner to catch it and prompt me with a list of available choices. What is more, it randomly hung up completely, exceeding the maximum response time, forcing KWin to kindly ask me to kill it.
