Thank you for the PR!

My first time writing Go code, so it will probably need some polishing. ;)

Tried to do my best to explain some comments so that you benefit by learning some Go today 👍

The Makefile automatically added the new library to two dependency files — I assume that's okay/intentional?

Yes, it pins dependencies to the exact versions, so if it works for you, it is guaranteed that it will work for everyone else, even if dependencies change over time and the code will not work with newer dependencies.

I only generate a single notification object and show/close it as appropriate. Works fine with the dunst OSD service, but maybe other services don't re-show notifications that existed previously?

I tested on mako on Wayland and it works exactly the same, so I think it's safe to assume that your logic is good - if not, someone will eventually report a bug and we will deal with it then 😉

Thank you for the helpful feedback! :)
I've added your suggestions and marked the comment threads "resolved" (my screen was getting a bit crowded). Github should allow you to reopen them, right?

It's awesome, thank you very much for your contribution!
