Hi there, I like this mod, but I dislike that the config item is shown on start, item screen and pause. Please add option to hide it. If I want to config, I go to the config files on my pc

Install ModMenu, the config icon is only shown if modmenu isn't present.

will you accept a PR with my solution, configurably not shown, having it shown by default if no mod menu is present?

No. The config system is used in all of my mods, more than 10. It would be a huge hassle to do that in all mods, most of which have versions going back to 1.14, and break the expectations of all those mod users.

First of, adding a config option that defaults to the old value doesn't break anything.

Secondly, the icon is intrusive, this is just a boolean flag to change, and the answer to a boolean flag change should never be "Just install mod X to change the flag."

I apologize for my rudeness in the previous post. I don't know why your No has tilted me that much. It is your mod to do with as you wish. Have a nice week :-)
