It's very hard to see the border between two overlapping green bars now.

[pbakaus, 2014/09/10 11:18:15]

True. Will fix.

[dgozman, 2014/09/09 14:46:49]

This gradient scales when you resize DevTools/browser. I don't really like that.

[pbakaus, 2014/09/10 11:18:15]

Agreed. Will fix.

Don't you think this is too small?

[pbakaus, 2014/09/10 11:18:15]

Nope, I think that size works really well. The font needs a minimum margin above
and below the bar if it is overlaying and 10px is the sweet spot.
