On the Desktop version you can have a file open and assign an "issue" to a specific spot or file that is assigned to that file directly. The mobile version requires you to exit the file, open the issues tab, create an issue, and then assign the file to it. Why not add the issues option directly to the file?
I noticed this already works on PDF's, but why not add it as a feature to .idw, .nwd, and .ipt files? (Specifically, regarding Mobile App)
