Is there any way to collapse/expand a group with single click?

Currently I only see double click, or click that arrow icon on the left to collapse/expand a group.

@zeroarst I don't think there is a way to do this directly with TST. (@piroor would know better if there is a way)

However, it does seem like you could create a helper addon via the TST API to listen for click events and then toggle if the tree is collapsed or expanded: Get tree information for specific single tab, Listening of notification messages, Collapse expanded tree, Expand collapsed tree
