It feels like widgets are being out-phased in general. If you want a flexible task manager (you can tailor filters to pretty much anything, including what the widget is displaying) try https://tasks.org/. It is open source and syncs with Google Tasks, meaning you have also free web interface for your tasks. If you are also using Gmail, it might fit your overall workflow nicely.

It is free but has a cheap premium that adds mostly cosmetics. I use it myself for years and I don’t really miss anything.
