Each file in this commit exhibits a problem where a variable is made in
some way but never used. This is a tricky problem with Qt since almost all UI forms are made but not used (like QLabel). But I am pretty confident that these changes are correct and do not have any aspect of a change to the UI. In most cases, there are just variables that are made and then copied over (like in iteration over lists or assignment of pointers based on conditionals).
