The racial and skill feats made me thinking once again about more granular feats and proficiencies.
Idea: double proficiency
If you are chosing a background that gives you proficiency in a skill you already chose from your class or race, once you can forfeit chosing a different skill and instead add double your proficiency bonus.
This way it may be possible to have expertise in a single skill.
(I limited it to once, because otherwise a rogue could have more expertises than skills later on. You may instead allow a rogue to pick a new skill if there is no skill left to apply expertise on).
I don't think it devalues the rogue's expertise because it just translate in another skill which is worth as much as expertise.
Idea: illiteracy
1) at character creation you may chose to be illiterate. Chose a proficiency in a tool for each 2 languages you are proficient in.
2) if you are literate and chose a background that gives you proficiency in a language, you may chose 2 languages written in a different alphabet than the languages you know. You can only speak and understand those languages.
