I'd rather that there is only one version of a launchbar and a taskbar
in the panel. By this I mean that the plugins 'launchbar' and 'taskbar'
should be removed, and we should come up with a good way to upgrade from
them to the 'launchtaskbar'. Users should not be required to actively
change their configuration.
I'll try again later. There have been some changes in master that change
lxpanel_launch_app(). Can you test with the newest master merged?
BTW, I have been contemplating removing the "lxpanelctl restart" option,
as it seems rather useless. Any comments?
