Okay, so here is what I have so far of my edited battery gadget.
(I'm fully editing the one I already had. I checked and the license on it is public, so editing/redistributing is fair game.)
Link to download: GADGET
Here's what I still want to add/modify
;Different fonts (just didn't do that yet, lol)
;Add estimated time remaining until low/critical levels are reached
I might do more.
