Given recent issue -

additional image file type(s) - HEIC specifically, should be integrated into Sketchbook and Autodesk Programs in general.
In much the same way VLC (and other video players) had to integrate h265, MKV, etc... - EFFICIENTLY - over the past few years.
And before anyone suggests that a HEIC file and JPEG are interchangable --- a RAR file is the "same" as a CBR or CBZ but not every program's coding understands that to be the case.
And while I may change the file extension - that is only helpful if the program/OS combination I am using doesn't immediately ignore it.
