Some minor improvement (?) suggestions:
- as Scott said: changelog would be nice to have (not sure if PK supports this, though)
- maybe the timestamps should be displayed as relative dates (”yesterday”, “3 weeks ago”…)? I’d like that better than the usual absolute format, but see two points to think about: a) sometimes people want to see the absolute date – maybe display it as tooltip? b) what happens if the window is left open over night – for correctness, the relative dates would have to be adjusted, which might be lots of work for a very rare event…
- nice hidden feature: it would be nice to be able to copy the contents of a row (Ctrl+c, or maybe a context menu entry?); most people won’t notice or need this feature, but _if_ somebody needs it, he will curse PK under his breath while typing the contents manually
- the filter button should have an icon; or maybe there shouldn’t be a button at all (like in Rhythmbox)? Didn’t find anything about this in Gnome HIG, unfortunately (anyone knows how to submit topic suggestions for that document, btw?)

All in all, great work!

Perhaps a | installed | removed | updated | all | combobox could be added to the filter, if you e.g want to see what packages you have installed and removed manually, for bugreports, dependencies etc. ?

This sounds useful but it’s not at all obvious from that interface.

If one has to right-click to reveal a “rollback” menu choice, might I suggest a button (which is clickable when one selects a package and only if the current backend supports rollback) instead? My experience with novice GUI users is that right-clicking is almost always news, not something users think to do.

Thanks for all your work on this project.

Having said that, I agree that things like duration are not important enough to be included in the main table.
