-Collection Manager
+Using CollectionManager you can edit or create your osu! collections in various ways:
+- creating new collections using Beatmap listing view along with beatmap drag&drop support(drag beatmaps to a main window collection)
+- Generate new collections from other players top100 rankings
+- Merge(join) multiple collections into one
+
+When creating this application my main intention was to be able to share ones collection with other people, and that's what it essentialy does: you can export your collections list to an .osdb file with other side can just import.   
+If they happen to be missing any beatmaps from your collection they'll be informed about it and be able to download missing beatmaps using built-in map downloader
+
+it can also help you with generating beatmap lists in various formats like osu forums or reddit posts and others.
