The cross-platform Mac and Windows feature is most valuable. I can do all sorts of stuff with this tool. It has got all sorts of automation capabilities. I have used some of them, but I have barely scratched the surface of what it can do on automation.
It is user-friendly, and it integrates well with other products. There are other third-party options that you can buy or in some cases, download for free to even extend it further. I use one or two of those.
