Great package manager!
Under
Cocoa: the buttons at the bottom have some display issues.
Either some buttons are displayed overlapping the list of packages, or the buttons do not show at all.
Moving the mouse over the area where the buttons are supposed to be, makes them (mostly) visible.
(see attached screenshot - using Lazarus 1.9.0 r58960M FPC 3.0.4 x86_64-darwin-cocoa (alpha))
This doesn't prevent me from using it (love it!), as it's just a cosmetic issue. Just thought I should report it.
