[Feature Request] Default collapsed setting for groups

[ezstewart96]

Currently, groups will retain their opened/collapsed status from previous use whenever you open a new tab. I have some groups that I always want opened when I open a tab, and some I would like to default to closed even if I used them last time. I think it would be a nice setting to have for each group to choose if it defaults to opened or collapsed, or retains the current functionality of remembering its previous state.
