I found twice yesterday that my phone was off in my pocket, not sure why. I installed lockdevice1.6 after that and it hasn't happened since,

I like having the time in the taskbar all the time, but that seems mutually exclusive with the battery indicator. I like both including the 1% increments on the power. Any chance you could make that happen?
In terms of leaning it down, do you notice any change in performance when you run things from internal storage instead of main? I would think ideally you would want to run as much as possible from internal storage (unless you see speed degradation due to differing access speeds) but of course that would mean they wouldn't be on the rom, probably sashimi installed to internal storage instead. I would think that could make a blazing fast system with massive free memory. I would therefore, leave out all the big programs you typically run and have cab's for windows live, bing, google maps, opera, even IE & office if you have cabs for them (I don't).
Have you tried bing3? I love the navigation feature, it's the only free talking navigation software I've found!
Just so I know, is this rom 6.5 or 6.5.x? It's been so long since I flashed, I'm so confused! I'm liking it though!
