Maintain state of Stash reveal arrow in Branches pane

I like to see the list of stashes awaiting my attention, so I always keep the "reveal" triangle open on the "Stash" list in the "Branches" pane. However, SmartGit keeps closing it for me.

- If I close and reopen the application, the list always reappears closed.

- If I delete the last stash (the "Stash" list disappears, which is fine), and then add a new Stash, the list again reappears closed

It would be nice if SmartGit remembered my preference and kept the Stash list at its previous state.
