In the midrange, there's Adobe Premiere Elements, which is cross-platform between Macs and PCs, and offers a lot more features and lots of help with creating effects. Professionals and prosumers have powerful, though pricey options in Final Cut Pro X and Adobe Premiere Pro. Final Cut is a deceptively simple application that resembles iMovie in its interface and ease of use, but it offers massively deep capabilities, and many third-party apps integrate with it for even more power. It also makes excellent use of the Touch Bar on the latest MacBook Pro, as shown in photo above. Premiere Pro uses a more traditional timeline and adds a large ecosystem of companion apps and plug-ins. It also excels in collaboration features.
Another feature that's new to me coming from a T3i that I love is the grid that you can have showing in the view-finder. Before you had to buy a replacement viewfinder eye-piece to get a grid and they didn't offer one for the T3i. Now it's done digitally and it's awesome. My only gripe is that you can't actually customize what grid pattern you want. But it's definitely a step in the right direction.
The second big draw is communication. The app creates a unified inbox for comments on Facebook and Instagram and messages from Messenger, so that you don’t have to bounce between different apps in order to respond to people. The app doesn’t seem to cover every possible messaging vector inside of Facebook’s services, but it sounds like a handy start. <<
