Using the Function Editor tab, you can create a Python function providing new expression functions to use. This function is stored in the user profile folder.
It could be nice to be able to remove unneeded functions (because they were tests eg) directly from the Editor tab, either from a contextual menu or with a provided button. Currently, you need to go to the folder in which the file is saved (which is not a common/easy place to reach - I personnaly struggle to access the AppData folder on Windows)

If you need to get the location from inside QGIS you can use the Settings -> User Profiles -> Open Active Profile folder..

I have started working on this but have some issues with the QFile::remove not removing the file.
