I am aware of the 'Recommends' and 'Suggests' thing. Many users are
familiar with it, and know how to go and seek out and install a missing
But this is about user experience. It just strikes me that there is a
level of automation that would be really pretty simple to implement:
"click here to install the missing package". Then the user's experience
is transformed from "right. i have to stop what I'm doing and put on my
sysadmin hat" into "ok, I'll just click this to download the plugin".
I had something along the lines of "gksu apt-get install
python-matplotlib" in mind, but I would like something that did the
install bit with a GUI if possible. And it's just an idea; I don't want
to do this unless it can be done in nice tidy way.
Another thought: doesn't Totem have some kind of 'codec finder'?
