Hi kevin
There are several ways to install and load extensions/applications, try using
Apps > Maintenance > Onboot / Ondemand Maintenance
tce-load -i extension_name
tce-ab
If loaded via "Onboot" then the icon will appear on reboot
if loaded via "Ondemand" then the icon will appear when loaded
wbar Icons are dynamic, try not to manipulate them .
Use wbar-config to remove icons from displaying (not to add them).
Also use wbar-config to change wbar appearance but nothing more..
Additionally, it helps to have persistent storage
clear as mud?
