Thanks imaginaryenemy. That's good to know applying tweak again (in this case, perhaps the unrestricted-ui Option "0" in wiki) should be harmless. May be I just did not see it coming up in "settings" the first time..

And also for confirming it only has % option, not icon and % option. As it was before, perhaps, the wiki is outdated and hence inaccurate in this regard.

Greendts - yes, I found that out, and tweaked a few settings there - such as a green/amber/red line for battery % too... it seems to give a lot of options... just need the time to work through them now...
