The slanck pre-beta is a first version of slanck, which is not yet in a beta stadium, since not all functionalities are implemented yet. The version is constantly under development. The development process is highly agile - the system is being updated several times a week which includes both new functionalities and bugfixes. If you are interested in specific features, just write an e-mail to firstname.lastname@example.org and we will see, whether there are possibilities from a product strategy perspective to implement them soon.
Although many functionalities are already implemented, of course the term "pre-beta" states, that several things are still missing.
