You have a class in a unit that contains other classes not related in function.
Move the class to a more relevant unit.
To move a class from one unit to another, place the cursor inside the declaration of the class or within one of its methods. Invoke the Move Class refactoring from the editor context menu or the Edit menu. The Move Class dialog will appear.
The Move Class dialog shows the name of the class to be moved, and any Delphi units that are open. If the unit you wish to target is not open, you can select it with the Browse... button. After selecting the target unit. Click OK. The Refactoring Explorer will appear.
The proposed changes will appear. You can inspect this list of changes (double-click a change to go to that location in code) and deselect any change that you do not wish to make. Click GO to make the selected changes, and the changes will be applied to the code. Recompile the project and test to ensure proper functionality.
Note: You may wish to run a code formating tool on the involved units after invoking this refactoring.
