So I'm writing a new edition of an old textbook, and I need some way of keeping track of what needs to be done, and what I have done.
I could use paper - but I tend to lose that. Or even a plain text file, but that would get confusing.
Is there any software which is helpful for something like this?
For what it's worth, I'm using LaTeX under Linux - so any software I use will have to be either cloud-based, or linux-based.
