+too much code. use draft instead! ******
+- In select mode: when i click on an image and hold shift, i want to be able to select multiple objects at once.
+- the function to generate textures is created but not connected to the buttons generate textures. the buttons are connected to the wrong function. 
+- when i click on them an image want to upload. the undo and redo button should be aligned right
+- the Y: coordinate should show always the position of the mouse arrow. currently after placing the plate, it stays at the point of the plate, but updates not to the mouse arrow position.
+- it should be not possibel to mark text.
+- add a botton at the top to create animation. when the user is clicking on it, it sends a message to Gemini-2.0-Pro. "This function is free for subscribers!"
+- add a progress bar (for the time it generates) every time the user requests something with an AI
+- when I generate something in the AI generate panel, show the .obj or .json code in the text field where I typed in the text.
+- add a button to generate video.
+- add a button to generate animation.
