Shouldn't future work like this just go into the backlog of your ticketing system?
The author mentions that a lot of these will eventually end up in comments or elsewhere, but it’s nice to capture random thoughts without adding the friction of deciding where it should land, what priority the ticket should be, etc, etc is quite nice.
I write notes throughout the day. Hardly ever search back in it. It's just to let me stop thinking about thing X while I'm working on thing Y. If X is important it'll come up again or show up in a ticket somewhere.
