After a difficult year and heavy development in the last six weeks, MoreWaita v47 has finally been released.
Bringing updates to over 100 icons, 50+ new app icons, over 20 new custom folder icons (largely thanks to @hasecilu), and a few new mimetype icons, this release also changes the folder structure to match upstream Adwaita. Any custom folder you've set before will break with this update, so you'll have to reassign them.
