HTC Eris :: Froyo Pattern-unlock / Manage Apps Hang And Battery Life

I'm a very happy KaosFroyo 37 user, but I have some misc questions.(sorry, this item is a sort of double-post) Do any of these lockscreen widgets work with Froyo? When I was running Android 1.5 and 2.1, I would keep my screen pattern-locked most of the time, since it lives in my pants' pocket and I want to avoid it activating accidentally. Then when I get into the car and place my phone in a cup holder, I would unlock the phone once and click a widget which would leave it unlocked (for easy access to GPS, etc.) for the duration of my ride, when I would lock the phone again and put it back in my pocket.Now with Android 2.2 I can't do this with the lock pattern, because apparently the security mechanisms don't permit it; one must re-enter the lock pattern several times, which is very time-consuming. Is there another approach for 2.2 users? I don't need very strong security, just want to avoid accidental phone calls and other accidental activations.
While (Android's) Manage Applications worked for me initially, now it only works the first time after a reboot. I.e., I can run it once, but on any subsequent attempts it will hang while attempting to populate its app list. As workaround I purchased Quick App Clean Cache, which is nice in its own right, but it would still be nicer not to have this problem. Also I'm not 100% convinced that Quick App Clean Cache is always giving me the complete set of options for an app, e.g. to move it to an SD card. Have others encountered this problem? I could probably generate a logcat for debugging purposes.

Most apps will let you move them to the SD card in KaosFroyo 37, even though I haven't checked the CyanogenMod option to permit these.I guess that there are a few more apps which might copy more completely to the SD card if I used this option.Can anyone shed any light on this option and whether it's saves any memory, and whether it induces any instability?I'm always careful not to copy widgets to the SD card.Battery life is a continued mystery; clearly much worse than before I rooted. Apparently the CPU tweaker isn't recommended (I guess it uses too much battery life trying to figure out whether it needs to adjust the CPU speed), and the battery life tweaker on the XDA forum described doesn't provide a very clear strategy. What do folks recommend? [ Correction: I had read a pretty incoherent writeup somewhere on XDA, but now see Collin_ph Battery Tweak RC1 for Cyanogen / Darch Froyo roms (possibly others) - xda-developers which is well-written. I will try this approach, but welcome your experiences.
