am thinking about installing next release just for these features:

1) the 4% battery-drop
I read the post about 4% and wonder why this - Condition: Battery Level, min 0, max 8
Wouldn't this cause a loop of script recalling when <8%? Why not exactly 4%?
From what I know, I'd set it to 4% and ignore everything above or below... what works best?

2) restrict cellular mode to 2G when at home (good signal here)
... this is to save battery, because 3G drains more, right?)
How can I make shure I switch to 2g only when at home without the need to be connected to my WLAN permanently?
I suspect if I use location based conditions (cell tower id), the places in close neighbourhood (around the next few blocks in town) will give me 2G only?
Can conditions like (WLAN) and (cell tower id) be combined to result something?
Is there a possibility for periodical check of (WLAN)?

3) disable smartsearch
Could the start of smartsearch background process be tied to opening search app (and stop at closing search app)?
This does not affect indexing for copied content like media etc, right?
