When laying out a track it should snap to a pin providing the feature
is turned on, which it is by default.
Check:
preferencs>general
In the bottom right hand corner there is the options for magnetic tracks,
it is normally set to When creating tracks.
For your connector, you should use a pad as the connection point. Place a
pad then adjust the size of it to suit your requirement. (I assumw that
you have done this)
On the Eeschema drawing are you trying to connect a wire to the round
circle of a power port? If so that could well be where some confusion has
crept into things. On a power port, the connection point is at the end of
the short line for most of them, For the ground (triangle) power ports
the connection is in the centre line of the long side.
+5V and Vcc is a NAME depending on where it is used it can be power in or
out.
Treat the power ports as invisible named nets, all you have to do is
ensure that the parts you design use the correct name, and then you
need to ensure that these invisible nets have some power fed into
them, which you do either by connecting them to power out pin on a
device, or you hang a power flag on it the tell the system that it is
powered.
It would be a good idea to run through the tutorial a few times...
As for the libraries, unless you have added extra libs and modules via
the libs and mods preferences menu, AND saved these into the default
project, anything you create and add will only be available in your
current project.
Start a new project and have a look, you should not see anything you have
designed. So you could run the tutorial from there.
