You try to use it like an expert, I am talking about beginners and
people who are new to circuit drawing.
For them it is very easy to start to use as it is simple to start
dragging components and connecting them by drawing lines.

Absolutely, but you could use a broadening of that target base.
A program needs all kinds of users to create a big user base.

Agreed, and there is no "wire button" in EWB, you just draw lines from
one component to the other, without setting it to wire drawing first.
Maybe you confuse it with some other program.

Seems like you have done a lot of things right.
I agree with most of your reasoning here.

I hope you realize that your intensive use of superspice makes you
somewhat unsuitable as a judge of the user interface or beginner
problems, you know too much to see how a beginner would approach your
It is better to ask the new users what they think.
This reasoning is the same for all programs, I have not tried your
program for a long time, so I talk about programs in general.
Very experienced users, or the programmer himself, might not see how
complicated his program is for the newcomers.
I have seen that a lot.
