Rejoin clan button

This hasn't happened to me but I've had several clan mates that have accidentally left the clan because they hit the wrong button, or their kid was using their phone/tablet and the kid left the clan.

For open clans rejoining isn't an issue, but for invite only or closed clans it can cause issues. (Especially if you don't know anyone in the clan from outside the game)

When someone leaves a clan there should be a grace period where they can rejoin the clan. 5 minutes? 15 min? Not sure on the length that it should be, but minimum of 5 minutes.

If you join another clan, the 'rejoin clan' option goes away since you're in another clan.

This grace period would not go I not effect if someone is kicked out of a clan.

Not a idea I think is necessary, but if Supercell has the resources, why not?

I like it, but if your a loyal member there is no reason why they wouldn't reinvite you, but I understand what you are saying. If Supercell has the time, I can see it happening!
