Im designing a 4-layer board and need to have one of the layers as GND copper area, second Signal GND copper area on another layer and third layer with Vcc copper area. Currently, in Copper Area Manager i can BOT set more than one Copper Area for the entire board. Im not sure if this function ever existed or it`s under development, but at the bottom of the Copper Area Manager window there are buttons MOVE UP and MOVE DOWN for multiple copper areas.Similar to other menus in EasySDA, there should be a green "+" button at the end of the first line, so that more lines could be added for multiple copper areas. The "+" button is not there and there is no other way to set a second or multiple copper areas. Of course, i did select 4-layers in the Layer Manager. I also tried selecting 6 layer PCB to see if that will allow for more of one copper area, but no. Is this a bug, is it an option under development or it will never be there?
