Thanks for your reply.
Yes, auto annotating components was also one of my questions a few weeks ago.
Beside the nightmare of Eagle's editors, it is fine for this. From the first resistor you drop, you can switch immediately to PCB, and it just exists.
But in Eagle, you're not allowed to remove a component from the PCB side, which makes sese. So what you were saying (it works well if there is only changes from schematic to PCB) is not an issue, I think, it can be done the same way, allow to add or remove components on schematic only.
'Feeling' sounds like you didn't try it, but just read about or see it being done.
Well, I tried. Sorry, I tried a few times, and one of the reasons I'm coming here for support is that I don't have 20 years experience with kicad, but a few weeks only. And on top of that not full time, far from that. Therefore I don't want to say "that's pure ***, it has to be changed", but rather say it's no more than my personal feeling at the time, implying that by knowing maybe 1% of the software, there might be a setting / preference I didn't find, etc...
And personally I don't export/import like mad when I do a schematic and layout. If you develop a circuitry you're in EEschema and once that is all right and mostly finished you go to PCBnew and take it from there.
Repeatedly adding/changing/removing stuff in the schematic and then modifying the layout all the time to track those changes sounds highly inefficient to me.
Exactly, that's the point. You say "personally", this implies your own experience. Others' experience might be different. And similarily, it sounds inefficient to you, but it doesn't sound inefficient to me.
Beside this, I'm not looking for constantly switching, It may happen that I miss a connection, a component, etc.
If you can do your design 100% right at once, I'm happy for you, but unfortunately it's not my case.
I believe there is a toolbar button in the nightly builds which does exactly what you want — generate a new netlist and open it in pcbnew without you having to do anything else.
Great! It looks like I'm not the only one to have that request. And if it keeps the tracks that are already routed, then I don't need more.
