Do we want to keep GNOME Logs in core?
Sadly, Logs does not seem to be in a good state. There is little sign of development activity, and issue reports are not being responded to. Also, when I've tested it, there are fairly severe bugs, like:
Aside from these obvious issues, there are also problems with the UI and technical design. I could provide an updated UI design, and we could try and find a developer to work on it. However, I also wonder if there is a market for this app (the number of bug reports would indicate that it's not being used much at the moment). I would personally use it occasionally if it worked, but I'm not sure how typical I am...
