I think having a tab you can add notes to for your convenience and having the ability to tab to it and even toggle it to be place on your screen would be a pretty neat feature. You know, give you the option to have it on your screen at all times for a note of your choice, or just not have it be there at all and be in an accessible place like Macros are. Like add a small note like "Unspoiled Mining spot in X at XX:XX am/pm" or "Plant X + Plant Y = Plant Z in crossbreeding". You know, just anything you would want to put in there for your convenience.
