✨ Terminal Utility: Tabs & Split View

Describe the solution you'd like

Being able to have more than one shell in a project would be great.

Please note the following behaviors:

• The plus icon adds a new terminal tab (not in a group).
• The minus button closes the selected tab.
• Press the delete key while terminal tab sidebar is in focus to close the selected tab.
• Drag an ungrouped terminal tab on top of another ungrouped terminal tab to create a group.
• Drag an ungrouped terminal tab into an existing group to add it to that group.
• Drag a terminal tab within a group to reorder it.
• Drag a grouped terminal tab to another group to move it to another group.

Describe alternatives you've considered
