I would say-

Mark something you haven't tested for long as Beta

Include good documentation in a text file on how to use it

Include an option to disable the mod in the mod options. It should truly disable just about all code by putting everything in a conditional that only runs if enabled.

Whenever possible use one of the built-in error checks for each input field.

I like to have mods inside a folder, the folder inside a zip file, so I can just drag the folder out of the zip file after I've downloaded it.
