Hi Ales and all! I did not noticed the entry in gschemrc, so the second proposal is not needed. The only difference after enabling promote-invisible will be that all hidden attributes will appear in edit menu (as device=, class= or so.) BTW: Is it good to allow the user to change a device= attribute? (Eg. to make a 74HC00, 74LVC00, 74ACT00... from generic 7400) W. Kazubski
