Option to hide all todos which are assigned to attribute groups

[ransome1]

Hi, some feedback after going from v1 to v2.

Its not possible to disable context filtering/sorting anymore when clicking on "Context" headline in drawer. I used to do it to quickly focus to tasks without context. These reside now in the bottom of the list and i need to scroll all the way down to see them or, alternatively, CTRL+click on all of my context labels. Both is tedious in comparison with the previous state. The same behaviour applies to all headlines in the drawer. They dont respond to the click like they responded in previous version, all they do is to hide or show labels.

Still missing sorting by name, eg. alphabetically.
