Facebook Video integration.
Better search such as Artist:Genesis. Instead of finding Genesis in every album, artist, song, metadata, bitrate (not really), etc.
Ditto on previous post: the ability to separate the playing now playlist according to a specified field.
Ditto on Set the ordering via sorting. Then right click on the zone name in Playing Now and select "update order".
Huge Ditto on Continuous playing of all songs by an artist, not just the current album. If JRiver can list all the songs in album/date order, we should be able to press play and have it work through the lot without having to create a playlist.
An Option to Automatically save EQ and Parametric EQ by file and by album - i.e., save last settings to the file or album. They are all mastered differently, and I have to adjust the sound every so often, even when I go back and play an album or file later on. Should be easy to implement.
Ditto on I can't tell you what I'd give for a simple album inventory list with/without album artwork. it should be more obvious how to do that.
Ability to transcode video to h.265 by "Convert Format" menu
The ability to grab the top of the JRiver window and drag it wherever you want, like to another monitor. At this time you have to click the little "Not Full Screen" icon, then move it.
Ditto on 64-bit support:
It made sense for MC to be 32-bit when madvr was limited to 32-bit, but now madvr has a 64-bit version, and with a memory intensive program like madvr this has added a very significant speed boost. This was actually the feature that finally sent me back to just using MPC-HC again.
The ability to more easily control deinterlacing in the MadVR video player. It's ludacris that many other players can do this quite easily, and it seems very hidden and not so functional in MC21.
Ditto on Artist perform a song in different constellations. E.g. Eric Burdon, Animals, Eric Burdon & The Animals...
Ditto on Volume leveling for gizmo
I'd really like MC22 to pick up IPC streams faster. I have to wait 5-20 seconds for a YouTube or Facebook video to hear the sound.
Ditto on Car Radio Playlist - Standard View.
Ditto on for any tag field I would like to be able to individually select and retrieve that metadata from the internet. So if I only want to get the 'Year' and not pollute all my other metadata, I could request that specific tag only.
That's my 2 cents for now :-)
