Feature request: Collapsible categories

Hi,

Here’s a new feature request:
We would like to be able to collapse categories om the CMSB admin view.

The best would be if we could collapse any category, a second option would be to allow to collapse any depth0 category (as they are usually the main categories).

By collapsing categories I mean, that we can turn this:

– Cat1
–– subcat1
–– subcat2
–– subcat3
– Cat2
–– subcat1
––– sub-subcat1
––– sub-subcat2
––– sub-subcat3
–– subcat2
–– subcat3
– Cat3
–– subcat1
–– subcat2
–– subcat3
––– sub-subcat1
––– sub-subcat2
––– sub-subcat3
– Cat4
–– subcat1


into this:
– Cat1 <click to expand>
– Cat2 <click to expand>
– Cat3 <click to expand>
– Cat4 <click to expand>


or like this:
– Cat1
–– subcat1
–– subcat2
–– subcat3
– Cat2
–– subcat1 <click to expand>
–– subcat2
–– subcat3
– Cat3
–– subcat1
–– subcat2
–– subcat3 <click to expand>
– Cat4
–– subcat1
