HiLauncher 1.0.
Developer just sent me the T600 version prior to release. Incredibly fast reponse from them. Love this launcher. Configurable "Start" menu approach to launching.
The Beta (v.1.1) is fully functional with the T600 5-way, public release 1st week of December. Developer now adding 1st letter launchable shortcuts (as in MS Start menu) and debugging a few minor issues. You can demo it (but no 5-way). I'm amazed at how deeply configurable this is. I'm using it in conjunction with colauncher (for the time being) and they are compatible. I've tossed out all my other launchers. Somehow, hilauncher seems extremely intuitive on the T600, almost as if it could be a native launcher. I've got the hotkey set for the screen HW button (press and hold) and the launcher “start” menu animates up, as in XP, way cool, and does not interfere with short presses of the HW button. In my left hand that is a very intuitive move. Totally one-handed launcher. In the right hand I would hotkey the phone HW button, press and hold
