Honestly, I'm just floored. I just had a friend turn me on to this program, and am practically giddy. I've been using AlbumWrap for so long, and to discover someone's figured out how to improve on the concept, and has cracked the ID3 tag bug, is a huge relief. I've waited for years to see someone come up with a way to edit the tags on a "wrapped" album without corrupting the index, and you've done it. Amazing! A million time, thank you.
So, since you seem to be on a roll, allow me to share the two things that are most often spoken of as either a wanted feature, or drawback that some people wouldn't touch this sort of program if it weren't "fixed."
1. A built-in playlist. I hear this one a LOT, and don't really blame them. The definite downside of having an archived album is that you can't skip to specific tracks. If it's at all possible to have that info embedded, so that it shows up in the player's playlist window for internal seeking, that would be marvelous.
2. Storing of non-MP3 files. A big want for years has been the ability to store additional things like TXT files (for notes, commentaries, lyrics, etc) and graphics (cover shots, etc). MP3Wrap already has this, but they've never gotten around to making a GUI, and using a command line for making albums with lots of tracks is a nightmare.
And I'll add a third item to my personal want-list: Either a unique player or, more preferably, a plug-in for Winamp, that allows _MIO archives with stored graphics to display the cover shot when played. (Heck, maybe this would be the way, via plug-in, to allow for a visible playlist on such archives, too.)
Well, that's it. If any of those things above are possible, they'd make fantastic advances to an already awesome program. Thanks again!
