Build me a Randomized Auto Mouse Clicker

Hi, I need an automatic mouse clicker that clicks on a certain pixel between a random time I set. (For example between every 3 and 5 minutes.) It also needs to have a log that shows the past intervals, like after I launch the program it needs to show when it clicked. And I want to add extra slots to perform more clicks. So after a randomized click, it will click on the pixel I select after certain seconds. (For example if randomized click is "n", the second click will be "n" + 5 second, 3rd slot will be "n" + 5 + 5.) I will decide if a slot is randomized or a set time. Lastly, I will need a save function, so I won't have to enter the same values every time I launch the program. Looking forward to your messages.
