many thanks for your contribution!

In principle this is a very useful addition. However, rather than adding yet 
another tab, I think this functionality should be merged into the "Install" 
tab (in fact, I think the "Update" tab should be merged into this, as well). 
For this, I would suggest to split the tree of packages into three subsections 
"Installed packages", "Updateable packages", and "New packages". This can be 
done by adding these categories as top level QTreeWidgetItems, and making all 
other items children of the appropriate category items.

Would you like to give that a try?

(While at it, one more idea would be to change the interface, somewhat, by 
allowing the user to check, instead of select, the packages to 
install/update).

Also, note that no additional cache for new pacakges should be necessary. 
Rather, you can pass the cache of available packages to new.packages(), in 
order to avoid a new download:
  new.packages(..., available= .rk.cached.available.packages())
See also the current .rk.get.old.packages().

Regards
Thomas
