OK, now that there's a script installer for a trial licence of Sitepad (waste of time/effort, IMO).
What's the point of a GUI installer when there's no means to remove the software?
Other than a manual deletion of all files with sitepad directories, what else needs to be done, rather than a complete re-install?

Like Softaculous and (horrible) netdata, there should be removal facilities in /scripts, if not in the GUI.
It really isn't that much to ask for.
