older Blue effects, improved (by adding Automation Lines if possible) and standardized. They all now have the BSB GUI.
Due to some changes in Blue some years ago, some of the older effects were no longer working. They are now up-to-date and improved and sometimes extended to have the same look as other effects in BlueShare.
If you'd like, you can ask for new Blue Effects ideas in the issue tracker...
Have a look at https://github.com/tjingboem/Blue-effects/wiki/blue-Blue-effects for more information on the Blue effects.
