API for App development would be an awesome feature. For example, found Tennis score app, but it’s useless for actual game (scoring system is wrong). Can’t contact devs directly, can’t fix it myself. Some sort of github with open source and community help would solve the problem and would not hurt stability.
System level access to developers is risky, but for simple apps with open source - I see no harm.
Such customization would greatly improve trust in a company and add actually useful stuff for all of the users.
