Connmann works fine for me, although the UI is ugly... And I feel that it is a bit feature limited. There is nothing to tweak out of the UI. I've never tried peasywifi so really no opinion on this. As long as wifi works out of the box i'm happy.
As for the wish list...
The "Web Browser" right click menu or through the app menu is annoying when using SB modules. All links try to open this, which say that I don't have a browser installed. Just not really useful with makesb. Maybe get this "web browser" a more "intelligent" script to detect if a browser is available? Or remove it and bundle a browser with AlphaOS (sb).
and I have issues with openbox. Intermittent freezes of the task bar and app menu that requires a reboot. Restarting openbox doesn't seem to help recover. I might be the only one... and i am out of luck since there is no new version of openbox.
