How about more comprehensive particle options? As it stands, you have two ways to create particles: entire file, and time-based range. I, personally, would like to be able to create them based on chapters--as in, specifying a beginning and end chapter (where you could simply enter the same value for both if you want a particle based on a single chapter). I also think it would be very intuitive if we could copy/duplicate existing particles, so that it will be easier to have different particles of identical passages for minor, switchable changes (different audio/subtitle tracks, for example).
In reference to the other thread about enabling full blu-ray support and the potential costs of doing so, how much work and expense would be involved in getting native Netflix, Hulu, and/or Youtube support? The letter tends to be very problematic because the website keeps changing, breaking the streaming functionality in MC, and it seems to happen with the release of every other build. Once it does begin to function, it breaks again within maybe a day. It just seems as if the current handling of popular streaming services equates to more in trouble than the worth of actual, licensed integration (though I don't know anything about licensing, so take that with a grain of salt).
