Hi! Thanks  a lot for the note tag and splitting the way to add more surface details. Could we add the surface:forward and surface:backward in addition to surface because they seem clearly defined with the general forward/backward suffix, just not used very much? The normal surface tag could still stay as a tag wtih the same  common/worst value, in order to only add correct information in addition for consumers who understand it without making it worse for existing consumers? Could that make sense, what are your thoughts?
