Adam Reichold proposed the following answer:
Hello jowind,

thank you for your suggestions. Concerning the individual points:

1 - We currently have only rectangular selection to copy text or images
which is triggered by using the "Copy to clipboard" action.

2 - You can tweak the behaviour of the tab bar using the settings, e.g.
to spread them out evenly, and much more extensively via an Qt
application stylesheet. There are various examples to be found in the
mailing list archives at [1]. Even though I am not sure who a non-
uniform size limits the number of visible tabs as text will be elided at
some point anyway if a lot of tabs are open.

3 - We currently do not this, as we want to limit the memory consumption
incurred by the user interface, i.e. we do not want to have separate
outline views for each tab, but have all tabs share the outline view.
This goes along with the fact we implemented them as top-level dockable
views, e.g. similar to the tool bars. So the only way to currently
achieve the behaviour described is by tracking the visibility per-tab
and adjusting this dynamically which I would like to avoid.

4 - Since qpdfview relies on external libraries to actually render the
document content, we probably cannot affect this directly. You could
check whether other Poppler-based PDF viewers have such settings, which
we could then also implement, but I am not aware of such a thing ATM.
Also if you are willing to do more research into the technical
background of these artefacts, we could try to develop a patch for
Poppler to conditionally hide these markings.

Concerning the first two suggestions, my advice would be to try a
different layout of those widgets, e.g. I personally prefer a vertical
tab in parallel to the outline view on wide screens. Also maybe
undocking the outline view is useful for you?

Please also note that the application is called qpdfview as qpdf [2] is
a different program to do quality-preserving processing of PDF
documents.

Best regards, Adam.
