 ## WIP

+### YACReader
+* Add setting to disable scroll animations and scroll smoothing, recommended if you are using a touch pad or if you find the mouse wheel behaviour laggy.
+
 ### YACReaderLibrary
 * Fix "Set type" context menu the grid view for folders.
 * Add a different versioning strategy for databases. DBs version will change only when the structure changes and not when YACReader version changes.
