For what it is worth, I liked the interface of rpmdrake from 8.2 better than the 9.0 9.1 stuff. I did complain about 8.2 at that time that I found the install/remove being on the same button confusing. But I find the current rpmdrake more confusing, being 4 separate programs with much related functionality: install remove mandrakeupdate and sources administration.
I would rather have all of that in one program/interface. Maybe you could look at synaptic for some ideas on how it could be done. And I am as an experienced user / mirror maintainer / software architecht for best dissemination of Linux wannabe - also sometimes confused about that I cannot find some software to install, when the package already is installed. best regards keld
