 ### TL;DR
 Basic information, with this application you can:
 - View all layers of a sliced (AnyCubic Photon Slicer or ChiTu DLP Slicer) file for the Photon 3D printer.
-- Easy see overhangs and unsupported areas (color coded in yellow and red)
+- Easy see overhangs and unsupported areas (color coded in yellow and red, in 2D and 3D)
 - Change exposure, off time and buttom layer settings on already sliced files.
 - Easy check if any part of a model is to close to the border
 - Quickly navigate beween problem layers and watch if it will break your prints.
 - Automatically fix pixel related unsupported areas (islands).
+- Manually edit pixels on the layers.

 ### What is a Photon file
 A Photon file is generated by the AnyCubic Photon Slicer (rebrand of ChiTu DLP Slicer). The slicer takes a 3D object and turn it into a list of images, each representing
