## [2.0.X] - not released yet
* fast annotation mode @todo
- keyboard input '123' denotes the following operation: select region 1, set 3 as the value of region attribute 2.
- if there is a single region attribute, the '13' sets 3 as the value of region 1
- if there are more than 9 regions, '1223' applies operation '23' to region '12'
- '0' is reserved to set the file attribute
- '023' assigns value 3 to the file attribute 2
- provide visual cues to the user when doing these operations (update bottom status bar as keys are pressed)
* image grid view
- cancel ongoing image load process
- add a "UNASSIGNED" group to denote all the files that do not have a value for the group variable
- preload images in adjacent groups to speed up visualization
- label subgroup of images in a group based on a certain variable
