> The inside of joins should look better now.

Thanks! And actually, I think I found the reason for my "hard to
make points appear" issue. And I think it might have been
resolved since. See the attachment.

I made that example in a version of Inkscape on Windows. As
you can see, if the control point was on one side, the pointy edges
would not appear. But moving them to the other side somehow
fixed the problem. So it had nothing to do with miter limit!

However, I wanted to make sure, so I took that example home
where I use Linux. By then the Linux version had been updated,
and somehow the points render correctly now regardless of
the position of the control point (did you fix something in the
meantime?)

Apart from that there's some rendering issues for large lines,
but those are extreme cases. It's definitely quite nice to use
now!

Now my main wish-item involves quickly accessing settings.
The most accessible way may be to have a drop-down option
for "Last powerstroke settings" (shorter name needed...)
Being able to save each settings and access them from the
toolbar drop-downs would be even better, but that doesn't seem
to be trivial to do right now.

Amazing work by the way!
