Balsamiq Edit: This has been implemented in version 3.5.3
I just realized you could add icons to lists - super super helpful and I love it.
The only catch is for the icon search the results are odd both for lists and for other inspector panel icon searches. Very odd.
When you use the quick add you get exact match first, starts with, and then alphabetical matches. Which is great - I know the exact word of my icon and can type 'plus' and hit enter with confidence.
For the icon searches, it's in some other order I thought was alphabetical, but it's not really. In my case, the exact match 'plus' is the very last item so I have to get to it every time I want to add it. Which if you're me making an accordian list...it's every item and gets very tedious fast. (Minus is the same and is the last icon in the list.)
Can you snyc up the order the icons appear in so it's the same as your quick add? Or at the very least, put exact matches first?
