Toggle, If/else are more advanced commands and not needed to get the remote working properly for your system. You can add those commands later to refine the remote. The Mx-900 doesn't have any of those commands and it is a very functional remote so don't let those functions concern you at first.
There are internet dealers that will sell the software with the remote. If you really get stuck there are services that will program it for you. Just like carpentry, some people can do fine work themselves, others start a project and realize they are over their head before they call a carpenter, and of course you have the guy that has no desire to do the work himself and calls a professional from the start. It is not as easy as the Harmony but once you understand it you'll be fine and if you have trouble there are options. So, it is not like you are stuck with a non-functioning remote if you can't program it or do not want to spend the time learning to program.
