@rantanplan you can do the debug from your pc, and still have the 7 in be fine

in config.js
set
address:“0.0.0.0”,
ipWhiltelist:[],

then u can connect to MM from your desktop and debug…
hit f5 to reload the pc MM page with the updated css…

use the bitvise ssh client, you can edit the files on the pi from your pc… by double click like on the pc
(enable ssh on the pi too)
