Hi BillieBlueberry and welcome,
WACUP is being developed by 1 person. From my point of view, it is a minor miracle that it exists at all.
It has been well over a year since the last public preview release. For better or worse, while dro has been more involved with the beta branch, he does keep a log of the reported public preview issues. The fixes and improvements on the beta side will eventually make it to the public preview side. Fixes for some of the current preview issues have already been found.
The beta and preview users help things progress by posting what works well and what doesn't. So please try to be patient and continue posting your issues with the public preview.
