For some reason my P&L Brain for windows is missing Thought icons.
My Mac seems to have the Icons.
But in V8 if you click on the left side of the Thought (Thought Icon) it would either open the link or attachment, or if multiple attacments it would pop-up a selection box to choose (This still works if there is a Thought Icon there).
Currently if there is no Thought Icon it is going into Thought edit mode.
