I am building a Mac app which shifts your cursor the screen you're looking at

I am a student and a software engineer and I use a double monitor setup but most of the times I get tired of shifting my cursor from one screen to another screen.

For example - If I am doing some work on my monitor and there's something that pops up on my machine screen then usually what I do, I think that my cursor will be automatically on the mac screen and try to click on the button on the mac screen but then I see that my cursor is on the monitor. So now I have to drag my cursor from my monitor to my Mac and then click on the button and then drag it again from my Mac to my monitor.

Yeah I know it may sound like a small issue but I think it is hogging my productivity if I am doing it a lot many times in my day....

Other than that: I am thinking of building something which will ease out the dragging process of one file from one screen to another.

And I have thought of more features too.

I am currently working on this SaaS but I want to know if this is actually feasible? Or is it just me that finds it annoying

And I think $7 monthly or a $60 one time price will be great for it. What do you think?
