currently we are working hard to enhance pamac to be come our official package manager go for. We already accomplished a simplified debian-like syntax via pamac-cli. Additional we provide python-bindings.
@guinux is already planing to document the needed syntax of the pamac source so a QT5-UI can be easily created. @Chrysostomus might start at some point with the QT5-UI, however other developers may also be part of it.
Would be great to push this project to the next level.
