Improve expand all and add expand and collapse all to the rightclick menu actions
|Target version:||020 - Next Release 2.0|
1."If all packages are collapsed, then indeed clicking on any "+" expands all packages EXCEPT the one that was clicked. And the clicked package (but not the links it contains) is removed from the selection."
-->Same with closing.
2."When you have a selection of several packages, some expanded (have a "-" icon to the left of their names) and some collapsed (have a "+" icon), it's unclear what clicking on any of the "+" or "-" icons does. I tried several examples but I cannot find a general rule."
-->All confirmed and yap, it's a bit confusing.
3.Add expand and collapse all to the selectable rightclick menu actions
