Maybe this is something that can happen by version 8, since once again a simple file browser that can be incorporated inside a patch is apparently too much to ask for. Instead, I'll be using those garbagey umenus to construct simple browser features, since I don't want to have to drag files from the edge of one screen to some part of my patch as a means of selecting them. It seems like the new "playlist" functions might be a somewhat useable part of a cludgey file selection interface, but apparently you have to parse them through a dictionary and a bunch of other nonsense to get a message you could send to an actual movie object. I'm seriously considering trying to crowdfund a project to just pay a developer to build a file browser, since I really don't want to have to learn a coding language just to get that functionality inside Max. I highly encourage C74 to spend 1/100th the time it has spent coding file browsing and search functions for the Max frame, and make something that actually works as a browser object INSIDE a patch. Until then, expect a frustrated screed like this with each release.
I have hundreds of files. These playlist objects don't even have scrolling for more then a few files visible at one time. Pretty much useless.
