In vertical tabs mode, it is difficult to determine if a collapsed tab group is suspended or not. For example:
is a collapsed tab group with two non-suspended tabs, where the parent tab is suspended. However, in the collapsed state, it can't be determined if the tree is suspended or if only the parent tab is suspended.
My suggested feature would be to put the crescent symbol next to the child tab count when the tree is collapsed, like this:
This second crescent will show up if and only if all child tabs are suspended. If a single one is not suspendend, the crescent symbol does not show.
When a user has a high number of vertical tabs, they may collapse some tab trees to save vertical space, and suspend some to save resources. This feature suggestion would help such users know whether a collapsed tab group is suspended or not at a single glance, instead of needing to expand them to check.
