I always took it to mean "One" like for expressions in English "you" or "we" for impersonal expressions, so I assumed "on" was impersonal pronoun for expressions of general usage. However, French like to use "Il faut" for impersonal expressions, or "il est important/necessaire qu'on..." A few years back I learned in spoken French it's used instead of Nous, nous being used in writing more often, so it's the personally "we" and the impersonal "we/one/you" recently I read that it can be used for personal "you." Is that right? The sentence was: "Alors, on se voit demain?" meaning "So, see you tomorrow" roughly, but literally being "We see each other tomorrow" instead of Eng: "I'll see you?", which would be "Je te verrai demain?" Why did they use "On" here? Is "Je te vois" wrong? Do you have to use the "on"?…
