Also one more question sorry, so sometimes when i try scrolling in with my mouse or panning it like gets reeeeeaaally slow and i can't zoom in all the way, it like gets super slow and eventually stops letting me zoom in? anyway thanks guys
Oh hey I actually figured it out, so you have to press Control+Shift and then press in on the Middle Mouse button and then just drag your mouse to zoom
