I would love to use plates like in Industrial Display Plates. https://mods.factorio.com/mod/IndustrialDisplayPlates
but with the features of attach notes :-)
The symbols are more clear on plates as on sign post and available in 3 sizes.
Is it possible (by your time) to add this plates?
no, not very well. You can not do the same as with Attach notes ;-) no map marker, no title. and can not be saved in blueprints.
so i thought just use the sign post item but with the graphic of the text plates. if that is possible.
