- Now ALWAYS all contacts are shown. I sort my contacts into differnt groups for better overview. Now this behaviour is useless. In older releases, when i selected a group in the left pane, i only saw the contacts of this group. Now i only can select or deselect the group. At now, grouping is meaningless.

Yes, this is the intended behaviour, because it fixes the most annoying bug in the previous versions - the search functionality. I've got a ton of requests such as "how to find a contact if I don't know where /in which collection/ it is stored?". The grouping functionality works also in the new version; e.g.: if your have 5 groups and unselect 4 of them then you will see contacts only from the 5th group (the addressbook checkbox will change to the "indeterminate" state). So all you need is to check the new group and uncheck the previous group...

Ok, I understand. Looks like the same behavior as Apples iOS calendar app.

- Contacts with company names are always grouped at the end of the "normal" contacts. Regardless if "globalGroupContactsByCompanies" is set to false or true. Maybe, i understand the function of "globalCollectionDisplayOrg" false. I thought, it would sort contacts with company names into the list according to the org field. F.e.: "ABC Company", "Mr. Bugs Bunny" is placed in the list under "ABC Company" not longer under "B" like "Bunny". Now i find "ABC Company" after all other contacts at the end of the list.

Will check and fix it!
