Filter
Collection of filters sorted to categories Points, Colors, Normals, Scalars and Mesh. General rule is, filters removing something are on top, then modifying and lastly adding filters, order from probably most used to less.
Undo/Redo
Filters operate on loaded points directly and since loaded points are not part of Blender data system, Blender undo system cannot be utilized. Because of that, very simple undo system is available. It is mainly meant for filters, but it is working also with tools etc, everything that change loaded point data directly.
Store state of point data with a button, then Restore if you want to go back to that stored state at any time, only one state is stored, it is cleared when new point cloud file is loaded, current unloaded, container object is deleted and renamed, when new blend file is loaded or when Clear button is pressed.
