@balloob could we get that merged?

@ximex it would need some more review

[pzich]

Yeah there's still some polish needed here. Hoping to take another look at this soon.

Can you remove the progress bar? Just entirely reuse the same log window "wireless" flashing uses?

Also, when flashing is done, start serial log immediately so we can catch the first boot after flashing.

I think it still makes sense to have this as a "user friendly" / less technical option.

I'm not sure if there's a good way to hand off the in progress serial log from the normal install dialog to the logs dialog. I'll try to see what's possible.

I'm not sure if esptool.js supports this, but I'll also try to see what's possible here.
