There are some selecting standards in Operating Systems: Ctrl + Click to select individual images, and Shift + Click for selecting a RANGE of images. This is possible in C1
BUT: If a range of images if already selected with Shift, I cannot ADD another range of images. Everytime I click Shift anew, the already selected images are lost from the selection. This behaviour is very annoying. Please allow that I can select more than one range, for example:
Images 1 - 5 (selected with the help of Shift Key)
AND Image 9 (added with Control Key)
AND Images 21 - 30 (AGAIN with Shift Key)
etc.
