[Local Files] Improvements

[GunGunGun]

Hi, I tried to use Local Files, and I think it would be great to have those features:

• Open local files in dialog instead of drag and drop, because in my case, my midi folder have 14 milion midi files, it's impossible to open this folder in any Explorer program because it'll hang forever, my only option is to paste midi path and open in File Selector (less important than folder)
• Favorite Local Files, this is good because marking local files is great for enjoying frequently used files
• Select and delete multiple local files, currently only 1 a time
• Folder for local files, this is absolutely needed because having folder just like favorite, allows us to categorize our midi, which is mandantory in case we want to separate between Pop, Rock, Video Game...

Just from my two cents, someone who enjoy midi and listen to them everyday instead of modern music!
