Over the holidays I took some pictures again; and a few of them needed stitching. Using Kubuntu’s Software Management System Settings in two minutes I was up and running with the version of Hugin that ships with Kubuntu 11.10.
However, I wanted the newest version, so I added the Hugin PPA to my sources list and within five minutes the newest and best Hugin was running on my notebook.
Like a real typical user, I did not read the manual, did not read the release notes, did not follow the conversation on the mailing list. As a consequence, I missed on the new tool, a vertical line finder, until I found it mentioned in the thread announcing the new release.
Upgrading users (the vast majority) has to go through a manual process of questionable utility and usability, possibly losing their preference settings to get access to the new functionality. Itchy. Scratch. Commit.
