 # A working tabulation of items that still need to get fixed for the next release of the library (TBD)
 
-* Logcat reports a warning with the demo application about only being able to 
-  request a single permission at a time. A suggested fix, thereby chaining a sequential 
-  list of permission requests on after another as they gradually return, is 
-  documented [here](https://stackoverflow.com/questions/42035244/getting-w-activity-can-request-only-one-set-of-permissions-at-a-time).
 * The gradient factory new instance / static generate methods are not returning the 
   correctly formatted Drawable instances. This is lower priority, but still needs to get tracked down. 
-* The library Activity toolbar navigation buttons to select new starting points for file trees 
-  by stanard path-type locations are not currently getting populated and then displayed. 
-  Right now, the LinearLayout does not expand to show the inflated drawable icons (though the 
-  onClick handlers for these buttons are presumably there if we could see the buttons 
-  to click on them). 
-* Need to set (reset) the customized, built-in file types versus folder (directory type) icons in the 
-  file items lists displayed in the RecyclerView.
-* The LHS FileType, file items layout displays have a CheckBox to select (if allowed) that file and/or directory 
-  entry to get returned to the client code. It currently is not working correctly.
-* Show loading files toast message while computing next directory contents.
-* Setup previous history up to the relevant root directory when initializing into subdirectories (e.g., Pictures or Screenshots).
-* The previous folder context history stack is going to get large: Can just replace it with a list of paths and
-  restore state from that?
-* Problem in demo app when launch the picker a second time (it freezes).
+* Themes customized completely by users.
