I use Trello to stay on task, easy to manage daily to-do lists while being able to just push everything to the next day and also managing long-term lists. It lets you comment, add files or links, create internal check-lists for each card, has the option for due dates, even integrations for stuff like Slack. It's great for keeping track of stuff in general. Plus it has a really friendly UI and it's free for the base package.
Asana is what we used at my last company and it's pretty much the same (at least from what I remember) with a different UI.
Another neat productivity thing I use is the Sketchpad app in the Windows Ink Workspace. My laptop has a touch screen that works with an active stylus. The app basically turns my laptop into a whiteboard on the fly (really handy for when I need to work out some complex math) and I can save a snapshot to then stick into Trello or wherever. Only gripe - Microsoft should add two-finger drag support (like in art programs like Krita) so you're not limited by you monitor size when using it.
