Subject: dump-asy: implement filtering by name, present nodes better
X-Git-Tag: 4.4~16
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e025f3b9e63c6e737e848bc824f7bcdaef66dd58;p=i3%2Fi3

dump-asy: implement filtering by name, present nodes better

where "better" means that we no longer use (name, orientation,
window-id), but "name" (leaf) or "name" (horizontal-split) for example.
