- Implemented filtering by group by using a dot as a seperator

- Added type sort priority to context sensitive search
- Now updating filters when populating groups for the first time in order to make sort priority actually work when opening context menu for the first time
- Fixed some cases where context sensitivity was applied even when context sensitive search was disabled
