How to add StatusBar Class and Use Grid Column as Border

I am new to learning tkinter and I am trying to make a simple tkinter GUI to run EXIFTool.

problem 1) When I uncomment StatusBar I get the following error; cannot use geometry manager grid inside . which already has slaves managed by pack. What is the best way to format my code to prevent this problem.

problem 2) How can I keep column 0 from collapsing so it acts as a border?

How to add StatusBar Class and Use Grid Column as Border

I get the following error; cannot use geometry manager grid inside . which already has slaves managed by pack

The problem can fixed:

On line 65, change this:

self.grid()

to:

self.pack()

On line 106, comment in StatusBar(app)
