I'm aware of "Go SWAP" which swaps all tabs of the source and destination displays. But what I need is to just swap the active tab of the source with the active tab of the destination display (leaving all other tabs untouched).
The only solution I've figured out myself is using the "Go" command and some variables to manually swap the pathes of source and destination tab. But I need to actually swap the tabs (e.g. to keep the file selection, the viewport position, etc.).
Or an optional argument to the "Go TABMOVE" command allowing to control whether the moved tab should be appended to the end or inserted beside to the active tab (e.g. on the right side).
