Suggestion: I added collision rendering that the character can walk on. Additionally, the polygons are visible on the collision surfaces. If the collision mesh contains too many polygons, we will be able to notice it, and if necessary, the file can be replaced with a more optimized version.
Suggestion2: Information about the selected objects is displayed in the corner of the program. Clicking the path opens the folder containing the file. This information about the selected objects can be disabled in the program options. When you hover the cursor over an object's name, its highlight changes color, and when you click it, the object is selected. This can be useful, for example, when deleting a specific object.
Suggestion3: After reducing the tree box, selecting objects in dense areas is easier.
