A couple of quirky display requests. on line 170 in extension.js, to format the 'canonical' time, you have it calling "%d%s%02d%s".format(hrs, hr_chr, hr_mins, min_chr); could that first %d be changed to %02d so we get the full HH effect? so "%02d%s%02d%s".format(hrs, hr_chr, hr_mins, min_chr);?
Also, when the line is actually set (line 300, could we add a space?) I have my Icon set to show percentage, and without the space, everything shows as too close together.
