Nice to have you back. We are still in a somewhat lengthy 0.3beta
cycle. Mostly waiting for translation work (I contacted the Launchpad
translators team for help.) and fixing the odd bug or two. We also see
some activity w.r.t. the Debian package.

I hope to be able to release soon enough. And I learned so much doing
0.3 that I think 0.3.1 will be a rewrite again. :-) But with under
10000 lines of code, this should not be too much of a problem...

With 'hidden', do you mean not visible by default? Because by now you
should be able to add all buttons you wanted and some more and there
should be icons for them. (If you have a FDo-compatible icon theme
installed. But always for the defaults and application-specifics.)

If not this sounds like a bug. Can you expand on what you mean by
'hidden'? Maybe with a screen shot?

This is way the other viewers do it. I know. Will think about it...
Not sure yet.

Putting them in different places. (De)Activating them independently.
Grouping functionality. Multiple tool bars seem to be too useful to
me, so I don't think I want to change that.

I think I found the problem: The document you sent is a bit odd in
that it specifies links like page 14 at -63% from the top. (And since
it is always -63%, I guess it is somehow broken.) The document view
then refuses to open a link to "page = 14, top = -0.63" as e.g. top is
expected to lie between 0.0 and 1.0.

Everywhere else this is enforced but I seem to have forgotten about
the outline. So I force the links into valid parameters as well by
truncating page and top and it seems to work as intended. (trunk
revision 314)

Yes, I can see those artifacts and know their kind. But I don't know
how to do something about them. This happens in the rendering which I
delegate to the Poppler library. Could again be rounding issues from
scale to DPI to integer dimensions. As I said I am not unsure if
anything can be done about it. (Besides changing the scale that is.)

Yes, it does not happen to me. Which does not mean there is no bug
involved in this.

All documents are refreshed after the settings are changed. Maybe you
could try to find out whether refreshing alone will trigger this
behaviour as well?
