I wish someone would pick it back up. It was pretty useful. It took some work to get it to run on Modern Fedora and I had a lot of stability problems with it.
FWIW, I don't recall a stability problem with it on Ubuntu 18.04 LTS. I exercised a lot of features, but I didn't use it for a long duration (CEO wanted to try having the entire company updating Instagantt).
At first glance, I wondered whether Gnome Planner was one of those open source projects that was started overly-ambitiously, and then quickly abandoned when development got difficult. However, after using it, I got the impression that Gnome Planner was mostly there.
Thanks for the suggestion. I did try Calligra Plan. I manage a lot of medium-small projects, and to ended up not fitting my workflow very well. That said, I could see how it might be perfect for people who manage and plan bigger projects.
