Thank you so much for replying, but that's not exactly it. I will try to explain more clearly:
I make a new label called Twitter.
It gets created with a default icon, but I change the icon to a star.
I then go to the Twitter app and label it as 'Twitter' so it shows up in the label.
Then in preferences, I set 'Labels with items in toolbar' to 'Twitter'.
Twitter now shows up in my notification toolbar.
The problem is it shows up with the default icon from the label, not the star that I set it to. Ive tried and tried to get it to show a different icon in the toolbar to no avail!
Id rather have it show the Twitter icon, but in the spirit of baby steps Id be happy if I could just get it to show the star...
