Hi! Hard to say what the best option is in the abstract — depends on your particular situation and needs. Most PDF readers (preview on Mac and Adobe on PC) allow you to add text annotations, so that’s what I usually do when I play games online.
I do know a member of the Gauntlet gaming community graciously created and shared a google sheet version of the playsheets that might also be helpful. Here’s a link: ESCAPE FROM DINO ISLAND ONLINE PLAY AID. You’ll need to make your own copy before you can edit it, but it’s pretty great!
