^ I also agree that the "countdown to import" feature is annoying. It's unlikely to be changed, but I'm not a fan. However, as Bill points out, it's no big deal. You can just clear the library and start over. It's one command:
File > Library > Clear library
Then you can set up auto import exactly as you'd like. You can read more about auto import in the wiki, here:
https://wiki.jriver.com/index.php/Auto-ImportMC may or may not suit you overall. If you're expecting a lot of really simple easy of use features and limitations like itunes, you may not enjoy the MC experience. But I can assure you that MC is FAR MORE powerful and configurable than itunes has ever been. It's better in every measurable way as far as I'm concerned. But I'm also willing to do a little extra work here and there to make MC work the way I want.
If MC and itunes were cars, itunes would be a self driving car that only drives in one part of the city, takes voice commands, and works the way you want about 80% of the time. It drops you off where you want mostly. But you end up walking through puddles sometimes, or going around the building when it drops you off at the back because it's map is wrong. The itunes car goes up to 40 MPH, but no faster. It's really a pretty decent car. As long as you don't want to go fast, get out of the city, or not step in puddles.
The MC car is a racer. It easily does pretty much whatever speed you want and can drive on any normal street anywhere in the country. You're in complete control and you have to pay attention. If you start texting on your phone at 80 MPH, you might crash into a pole. You can also park it exactly where you want and not step out into a puddle if you don't want to. It's not self driving and you can get lost driving it if you go where you haven't gone before. But YOU are in control of almost every aspect of the MC car.
The question is, which car would you rather drive?
