Feature request: “docking bars” / border tabsets (left/right/bottom/top)

[NexusUnleashed]

Dockview is awesome, especially the in-page floating groups. The one feature I’m really missing (coming from FlexLayout) is border docking bars: edge tab strips on the left / right / bottom / top for things like Navigation, Options, Output/Terminal, etc.

FlexLayout has this concept built-in as “borders” (tabs docked to the edges). It’s a super practical IDE/workbench pattern: keeps the main workspace clean, but tool panes are always one click away and can auto-hide.

Would you consider adding a first-class “borders/edges” feature to Dockview (with drag/drop to pin panels to an edge, persisted size/state, etc.)? For reference the FlexLayout demo shows border tabs: https://rawgit.com/caplin/FlexLayout/demos/demos/v0.8/demo/index.html
