I don't mind if the mappings are awkward. My final goal is to use the same set of mappings between my tiling manager. For instance with neovim, my tiling windows manager checks if the focused window is neovim, if it is, it relays the change focus commands to neovim so that I can move around neovim splits as if there were windows.
There should be mapping to change panels Left/Right/Top/Bottom like vim's wincmd.
