I am a registered (and very satisfied) Italian user of Hi-Launcher.
A few days ago I installed the version 3.4 and......the only difference I've noticed is that BEFORE I could "adjust" the backlight via 5-ways-key (on Hi-Launcher => "item tipe" => toggle; "toggle" => backlight) while NOW (with 3.4) I can only switch the backlight on/off (same as "function key" + "right shift" on any Treo).
Additionally - but this maybe because I have always KeyGuardExt enabled - when I set the backlight "off" on Hi-Launcher, it doesnt't stay "off" the next time I switch the display on....while BEFORE it did keep in the memory the backlight value I had set before switching off.
Do you confirm me it is now like this???
Actually the ability of "adjusting" the backlight was one of the things I used the most during my (working) days and it did help me saving a lot of battery power especially when I knew I had no chance at all to charge my Treo until getting to an hotel at night...
Last sentence is just a praise to your product as I've tried almost all Launchers on the market and for me no one could be more helpful, useful and easy-to-customize than Hi-Laucher.
