Hi James,
I enjoyed reading your post. You did a really nice job of explaining four different operating system applications. I am very familiar with Canva, as I use it for my job as a Graphic Designer and Media Manager. It is a great and easy application to use, to help with bringing designs to life. I absolutely love Canva! The other three I am not really familiar with. I have heard of Intuit QuickBooks, as several people I know use it. I have heard that it is a great tool. As far as Open LP, I have never heard of it. But, at our church we use ProPresenter. Do you know of it’s similar? I have never heard of Bitdefender, but it sounds like it would be a quality cybersecurity software application.
