i think the plugin menu had not yet existed before install ltplus. seems rb writer can choose location of script commands (per google help) also system restore removed uninstall.exe, but i now think sketchup installer never creates an uninstall.exe (because su uses msi?) to investigate further, i think i'll uninstall then reinstall su, observing file changes in app folde4rs install some extra plugins. install ltplus. i expect the earlier plugins will still show after ltplus install. IOW, i suspect that ltplus only "looks funny", but is likely OK.
