btv.panels
btv.panels.actions.open()
:lspanels opens a btvpanels panel listing the named panels (rows begin with the panel
buffer’s number). <CR> parses that number and :b-switches to it — but the current
window IS the panel window, so switch_buffer swaps it in place, showing that panel’s
last content (no close, no regenerating command). Contrast btvbuffers, which targets a
document and so closes the panel and lands the switch in the main window.
