Please add hotkey for resizing sidebar

Use case or problem

Resizing any sidebar requires reaching for the mouse and finding the 10 pixels of the splitter that allow to drag-to-resize the sidebar. It would be great to do this with the keyboard instead.

Proposed solution

Add a keyboard shortcut to resize (incrementally, bigger/smaller) the active pane (I guess last pane that was focused?)

There’s a shortcut like that in vscode and even though it could be a bit confusing (since it depends on the active pane), it’s a lifesaver for me.
