iMovie

Hi, I have been using iMovie for a long time now but recently it hasn't been opening and I read somewhere that I should update it, so I tried to but it wasn't updating, then I decided to delete the app and re download it, it worked but now the only way to find it is to go to spotlight search and then look it up, I was wondering if there was a way to get it with the other applications (like when on my mac I press f4 It brings me to something with all my apps, similar to an iPhone/ipad/ipad home screen).

Thank you
