So... Probably you invested a lot of time into this, but even after trying for several weeks, I do not understand how to use the new interface, sorry. I do not understand which icons mean what, as they have no description and no universal meaning. So I try to tap on them, trying to find the functionality I was looking for, but it seems to have disappeared. It seems like the whole functionality one could wish from a devtools extension has disappeared or should be here but isn't working. Very sad.
