Thanks indman for developing those symbols.
I think they are easy on the eyes, specially the bold ones.
I notice they are rectangular on the picture you kinldy shared, I'm not sure if it's because the different resolution on X and Y, and/or aspect ratio of the screen or something else, so just to confirm: It will be seen somehow square when displayed on the actual screen?
On the other hand, I also notice the SCRs are narrower than the rest, therefore it's just a matter of tastes, but you could move the G a little bit to the left on those. And on the same line of thinking, you could move the B of the BJTs a little bit to the right.
Whatever you decide, it will be very welcome.
